SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER CPU Central Processing Unit (CPU) The CPU has a total of 13 registers shown in Figure 1.9. Seven of these registers (R0, R1, R2, R3, A0, A1, and FB) come in two sets; therefore, these have two register banks. (1) Data registers (R0, R0H, R0L, R1, R1H, R1L, R2, and R3) Data registers (R0, R1, R2, and R3) are configured with 16 bits, and are used primarily for transfer and arithmetic/logic operations. Registers R0 and R1 each can be used as separate 8-bit data registers, high-order bits as (R0H, R1H), and low-order bits as (R0L, R1L). In some instructions, registers R2 and R0, as well as R3 and R1 can use as 32-bit data registers (R2R0, R3R1). (2) Address registers (A0 and A1) Address registers (A0 and A1) are configured with 16 bits, and have functions equivalent to those of data registers. These registers can also be used for address register indirect addressing and address register relative addressing. In some instructions, registers A1 and A0 can be combined for use as a 32-bit address register (A1A0). Figure 1.9.

SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER CPU (3) Frame base register (FB) Frame base register (FB) is configured with 16 bits, and is used for FB relative addressing. (4) Program counter (PC) Program counter (PC) is configured with 20 bits, indicating the address of an instruction to be executed. (5) Interrupt table register (INTB) Interrupt table register (INTB) is configured with 20 bits, indicating the start address of an interrupt vector table. (6) Stack pointer (USP/ISP) Stack pointer comes in two types: user stack pointer (USP) and interrupt stack pointer (ISP), each config- ured with 16 bits. Your desired type of stack pointer (USP or ISP) can be selected by a stack pointer select flag (U flag). This flag is located at the position of bit 7 in the flag register (FLG). (7) Static base register (SB) Static base register (SB) is configured with 16 bits, and is used for SB relative addressing. (8) Flag register (FLG) Flag register (FLG) is configured with 11 bits, each bit is used as a flag. Figure 1.10 shows the flag register (FLG). The following explains the function of each flag:
- Bit 0: Carry flag (C flag) This flag retains a carry, borrow, or shift-out bit that has occurred in the arithmetic/logic unit.
- Bit 1: Debug flag (D flag) This flag enables a single-step interrupt. When this flag is “1”, a single-step interrupt is generated after instruction execution. This flag is cleared to “0” when the interrupt is acknowledged.
- Bit 2: Zero flag (Z flag) This flag is set to “1” when an arithmetic operation resulted in 0; otherwise, cleared to “0”.
- Bit 3: Sign flag (S flag) This flag is set to “1” when an arithmetic operation resulted in a negative value; otherwise, cleared to “0”.
- Bit 4: Register bank select flag (B flag) This flag chooses a register bank. Register bank 0 is selected when this flag is “0” ; register bank 1 is selected when this flag is “1”.
- Bit 5: Overflow flag (O flag) This flag is set to “1” when an arithmetic operation resulted in overflow; otherwise, cleared to “0”.
- Bit 6: Interrupt enable flag (I flag) This flag enables a maskable interrupt. An interrupt is disabled when this flag is “0”, and is enabled when this flag is “1”. This flag is cleared to “0” when the interrupt is acknowledged.
SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER CPU
- Bit 7: Stack pointer select flag (U flag) Interrupt stack pointer (ISP) is selected when this flag is “0” ; user stack pointer (USP) is selected when this flag is “1”. This flag is cleared to “0” when a hardware interrupt is acknowledged or an INT instruction of software interrupt Nos. 0 to 31 is executed.
- Bits 8 to 11: Reserved area
- Bits 12 to 14: Processor interrupt priority level (IPL) Processor interrupt priority level (IPL) is configured with three bits, for specification of up to eight processor interrupt priority levels from level 0 to level 7. If a requested interrupt has priority greater than the processor interrupt priority level (IPL), the interrupt is enabled.
- Bit 15: Reserved area The C, Z, S, and O flags are changed when instructions are executed. See the software manual for details. Figure 1.10.

SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER Software Wait Software wait The wait bit (bit 7) of the processor mode register 1 (address 000516)(note) allows you to insert software wait states for the internal ROM/RAM areas. If this bit is 0, the bus cycle is executed in one BCLK (internal clock) period; if the bit is 1, the bus cycle is executed in two BCLK periods. This bit is cleared to 0 after a reset. The SFR area is unaffected by this control bit; it is always accessed in two BCLK periods. Table 1.2 shows the relationship between software wait states and bus cycles. Note: Before attempting to change the contents of the processor mode register 1, set bit 1 of the protect register (address 000A 16) to “1”.

SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER The following paragraphs describes the clocks generated by the clock generating circuit. (1) Main clock The main clock is generated by the main clock oscillation circuit. After a reset, the clock is divided by 8 to BCLK. The clock can be stopped using the main clock stop bit (bit 5 at address 000616). Stopping the clock, after switching the operating clock source of CPU to the sub-clock, reduces the power dissipation. After the oscillation of the main clock oscillation circuit has stabilized, the drive capacity of the main clock oscillation circuit can be reduced using the X IN-XOUT drive capacity select bit (bit 5 at address 000716). Reducing the drive capacity of the main clock oscillation circuit reduces the power dissipation. This bit changes to “1” when shifting from high-speed/medium-speed mode to stop mode and at a reset. When shifting from low-speed/low power dissipation mode to stop mode, the value before stop mode is re- tained. (2) Sub-clock The sub-clock is generated by the sub-clock oscillation circuit. No sub-clock is generated after a reset. After oscillation is started using the port Xc select bit (bit 4 at address 0006 16), the sub-clock can be selected as BCLK by using the system clock select bit (bit 7 at address 000616). However, be sure that the sub-clock oscillation has fully stabilized before switching. After the oscillation of the sub-clock oscillation circuit has stabilized, the drive capacity of the sub-clock oscillation circuit can be reduced using the X CIN-XCOUT drive capacity select bit (bit 3 at address 000616). Reducing the drive capacity of the sub-clock oscillation circuit reduces the power dissipation. This bit changes to “1” when shifting to stop mode and at a reset. (3) BCLK The BCLK is the clock that drives the CPU, and is fc or the clock is derived by dividing the main clock by 1, 2, 4, 8, or 16. The BCLK is derived by dividing the main clock by 8 after a reset. The main clock division select bit 0(bit 6 at address 0006 16) changes to “1” when shifting from high- speed/medium-speed to stop mode and at reset. When shifting from low-speed/low power dissipation mode to stop mode, the value before stop mode is retained. (4) Peripheral function clock (f1, f8, f32, fAD ) The clock for the peripheral devices is derived from the main clock or by dividing it by 8 or 32. The peripheral function clock is stopped by stopping the main clock or by setting the WAIT peripheral function clock stop bit (bit 2 at 0006 16) to “1” and then executing a WAIT instruction. (5) fC32 This clock is derived by dividing the sub-clock by 32. It is used for the timer A, timer B and timer X counts. (6) fC This clock has the same frequency as the sub-clock. It is used for BCLK and for the watchdog timer.
SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER Clock Output The clock output function select bit allows you to choose the clock from f8, fc, or a divide-by-n clock that is output from the P54/CKOUT pin. The clock divide counter is an 8-bit counter whose count source is f32, and its divide ratio can be set in the range of 0016 to FF16. Figure 1.19 shows a block diagram of clock output. Figure 1.19. Block diagram of clock output Clock source selection Reload register (8) Low-order 8 bits Data bus low-order bits P54 fC Division n+1 n=0016 to FF16 Clock divided couter (8) Example: When f(XIN)=10MHz n=0716 : approx. 16.5kHz n=2616 : approx. 4.0kHz n=4D 16 : approx. 2.0kHz n=9B 16 : approx. 1.0kHz P54/CKOUT f32 Address 038E16
SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER Pin States Port Retains status before wait mode CLK OUT When fC selected Does not stop When f8, clock devided Does not stop when the WAIT counter output selected peripheral function clock stop bit is “0”. When the WAIT peripheral function clock stop bit is “1”,the status immedi- ately prior to entering wait mode is maintained. Wait Mode When a WAIT instruction is executed, BCLK stops and the microcomputer enters the wait mode. In this mode, oscillation continues but BCLK and watchdog timer stop. Writing “1” to the WAIT peripheral function clock stop bit and executing a WAIT instruction stops the clock being supplied to the internal peripheral functions, allowing power dissipation to be reduced. Table 1.5 shows the status of the ports in wait mode. Wait mode is cancelled by a hardware reset or interrupt. If an interrupt is used to cancel wait mode, the microcomputer restarts from the interrupt routine using as BCLK, the clock that had been selected when the WAIT instruction was executed. Table 1.5. Port status during wait mode Table 1.4. Port status during stop mode Wait Mode Pin States Port Retains status before stop mode CLK OUT When fC selected “H” When f8, clock devided Retains status before stop mode counter output selected Stop Mode Writing “1” to the all-clock stop control bit (bit 0 at address 000716) stops all oscillation and the microcom- puter enters stop mode. In stop mode, the content of the internal RAM is retained provided that VCC remains above 2V. Because the oscillation of BCLK, f 1 to f32, fc, fc32, and fAD stops in stop mode, peripheral functions such as the A-D converter and watchdog timer do not function. However, timer A, timer B and timer X operate provided that the event counter mode is set to an external pulse, and UART0 functions provided an external clock is selected. Table 1.4 shows the status of the ports in stop mode. Stop mode is cancelled by a hardware reset or an interrupt. If an interrupt is to be used to cancel stop mode, that interrupt must first have been enabled. If returning by an interrupt, that interrupt routine is executed. When shifting from high-speed/medium-speed mode to stop mode and at a reset, the main clock division select bit 0 (bit 6 at address 0006 16) is set to “1”. When shifting from low-speed/low power dissipation mode to stop mode, the value before stop mode is retained.

Table 1.6 shows the operating modes corresponding to the settings of system clock control regis- ters 0 and 1. When reset, the device starts in division by 8 mode. The main clock division select bit 0(bit 6 at address 0006 16) changes to “1” when shifting from high-speed/medium-speed to stop mode and at a reset. When shifting from low-speed/low power dissipation mode to stop mode, the value before stop mode is retained. The following shows the operational modes of BCLK. (1) Division by 2 mode The main clock is divided by 2 to obtain the BCLK. (2) Division by 4 mode The main clock is divided by 4 to obtain the BCLK. (3) Division by 8 mode The main clock is divided by 8 to obtain the BCLK. When reset, the device starts operating from this mode. Before the user can go from this mode to no division mode, division by 2 mode, or division by 4 mode, the main clock must be oscillating stably. When going to low-speed or lower power consumption mode, make sure the sub-clock is oscillating stably. (4) Division by 16 mode The main clock is divided by 16 to obtain the BCLK. (5) No-division mode The main clock is divided by 1 to obtain the BCLK. (6) Low-speed mode fC is used as BCLK. Note that oscillation of both the main and sub-clocks must have stabilized before transferring from this mode to another or vice versa. At least 2 to 3 seconds are required after the sub- clock starts. Therefore, the program must be written to wait until this clock has stabilized immediately after powering up and after stop mode is cancelled. (7) Low power dissipation mode fC is the BCLK and the main clock is stopped. CM17 CM16 CM07 CM06 CM05 CM04 Operating mode of BCLK Status Transition of BCLK Table 1.6. Operating modes dictated by settings of system clock control registers 0 and 1 Note : Before the count source for BCLK can be changed from XIN to XCIN or vice versa, the clock to which the count source is going to be switched must be oscillating stably. Allow a wait time in software for the oscillation to stabilize before switching over the clock.
SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER Power Saving There are three power save modes. (1) Normal operating mode
- High-speed mode In this mode, one main clock cycle forms BCLK. The CPU operates on the BCLK. The peripheral functions operate on the clocks specified for each respective function.
- Medium-speed mode In this mode, the main clock is divided into 2, 4, 8, or 16 to form BCLK. The CPU operates on the BCLK. The peripheral functions operated on the clocks specified for each respective function.
- Low-speed mode In this mode, fc forms BCLK. The CPU operates on the fc clock. fc is the clock supplied by the subclock. The peripheral functions operate on the clocks specified for each respective function.
- Low power-dissipation mode This mode is selected when the main clock is stopped from low-speed mode. The CPU operates on the fc clock. fc is the clock supplied by the subclock. Only the peripheral functions for which the subclock was selected as the count source continue to run. (2) Wait mode CPU operation is halted in this mode. The oscillator continues to run. (3) Stop mode All oscillators stop in this mode. The CPU and internal peripheral functions all stop. Of all 3 power saving modes, power savings are greatest in this mode. Figure 1.20 shows the transition between each of the three modes, (1), (2), and (3). Power Saving

(Refer to the following for the transition of normal mode.) Power Saving
SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER Protection The protection function is provided so that the values in important registers cannot be changed in the event that the program runs out of control. Figure 1.21 shows the protect register. The values in the processor mode register 0 (address 0004 16), processor mode register 1 (address 000516), system clock control reg- ister 0 (address 000616), system clock control register 1 (address 000716) and port P4 direction register (address 03EA16) can only be changed when the respective bit in the protect register is set to “1”. There- fore, important outputs can be allocated to port P4. If, after “1” (write-enabled) has been written to the port P4 direction register write-enable bit (bit 2 at address 000A 16), a value is written to any address, the bit automatically reverts to “0” (write-inhibited). However, the system clock control registers 0 and 1 write-enable bit (bit 0 at 000A16) and processor mode register 0 and 1 write-enable bit (bit 1 at 000A16) do not automatically return to “0” after a value has been written to an address. The program must therefore be written to return these bits to “0”.

These bits can neither be set nor reset. When read, their contents are indeterminate. Note: Writing a value to an address after “1” is written to this bit returns the bit to “0” . Other bits do not automatically return to “0” and they must therefore be reset by the program. /LiteDiagLines /LiteDiagLines /LiteDiagLines /LiteDiagLines /LiteDiagLines /LiteDiagLines Figure 1.21.

SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER Interrupts Software Interrupts A software interrupt occurs when executing certain instructions. Software interrupts are non-maskable interrupts.
- Undefined instruction interrupt An undefined instruction interrupt occurs when executing the UND instruction.
- Overflow interrupt An overflow interrupt occurs when executing the INTO instruction with the overflow flag (O flag) set to “1”. The following are instructions whose O flag changes by arithmetic: ABS, ADC, ADCF, ADD, CMP, DIV, DIVU, DIVX, NEG, RMPA, SBB, SHA, SUB
- BRK interrupt A BRK interrupt occurs when executing the BRK instruction.
- INT interrupt An INT interrupt occurs when assigning one of software interrupt numbers 0 through 63 and executing the INT instruction. Software interrupt numbers 0 through 31 are assigned to peripheral I/O interrupts, so executing the INT instruction allows executing the same interrupt routine that a peripheral I/O interrupt does. The stack pointer (SP) used for the INT interrupt is dependent on which software interrupt number is involved. So far as software interrupt numbers 0 through 31 are concerned, the microcomputer saves the stack pointer assignment flag (U flag) when it accepts an interrupt request. If change the U flag to “0” and select the interrupt stack pointer (ISP), and then execute an interrupt sequence. When returning from the interrupt routine, the U flag is returned to the state it was before the acceptance of interrupt request. So far as software numbers 32 through 63 are concerned, the stack pointer does not make a shift.
SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER Interrupts Hardware Interrupts Hardware interrupts are classified into two types — special interrupts and peripheral I/O interrupts. (1) Special interrupts Special interrupts are non-maskable interrupts.
- Reset Reset occurs if an “L” is input to the RESET pin.
- DBC interrupt This interrupt is exclusively for the debugger, do not use it in other circumstances.
- Watchdog timer interrupt Generated by the watchdog timer.
- Single-step interrupt This interrupt is exclusively for the debugger, do not use it in other circumstances. With the debug flag (D flag) set to “1”, a single-step interrupt occurs after one instruction is executed.
- Address match interrupt An address match interrupt occurs immediately before the instruction held in the address indicated by the address match interrupt register is executed with the address match interrupt enable bit set to “1”. If an address other than the first address of the instruction in the address match interrupt register is set, no address match interrupt occurs. (2) Peripheral I/O interrupts A peripheral I/O interrupt is generated by one of built-in peripheral functions. The interrupt vector table is the same as the one for software interrupt numbers 0 through 31 the INT instruction uses. Peripheral I/O interrupts are maskable interrupts.
- Key-input interrupt ___ A key-input interrupt occurs if an “L” is input to the KI pin.
- A-D conversion interrupt This is an interrupt that the A-D converter generates.
- UART0 and UART1 transmission interrupt These are interrupts that the serial I/O transmission generates.
- UART0 and UART1 reception interrupt These are interrupts that the serial I/O reception generates.
- Timer A0 interrupt This is an interrupts that timer A0 generates.
- Timer B0 and timer B2 interrupt These are interrupts that timer B generates.
- Timer X0 to timer X2 interrupt These are interrupts that timer X generates.
- INT0 and INT1 interrupt An INT interrupt occurs if either a rising edge or a falling edge is input to the INT pin.
SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER Interrupts Interrupts and Interrupt Vector Tables If an interrupt request is accepted, a program branches to the interrupt routine set in the interrupt vector table. Set the first address of the interrupt routine in each vector table. Figure 1.23 shows format for specifying interrupt vector addresses. Two types of interrupt vector tables are available — fixed vector table in which addresses are fixed and variable vector table in which addresses can be varied by the setting. Interrupt source Vector table addresses Remarks Address (L) to address (H) Undefined instruction FFFDC16 to FFFDF16 Interrupt on UND instruction Overflow FFFE0 16 to FFFE316 Interrupt on INTO instruction BRK instruction FFFE4 16 to FFFE716 If the vector is filled with FF16, program execution starts from the address shown by the vector in the variable vector table Address match FFFE8 16 to FFFEB16 There is an address-matching interrupt enable bit Single step (Note) FFFEC 16 to FFFEF16 Do not use Watchdog timer FFFF0 16 to FFFF316 DBC (Note) FFFF4 16 to FFFF716 Do not use - FFFF8 16 to FFFFB16 - Reset FFFFC 16 to FFFFF16 Table 1.7.

- Fixed vector tables The fixed vector table is a table in which addresses are fixed. The vector tables are located in an area extending from FFFDC16 to FFFFF16. One vector table comprises four bytes. Set the first address of interrupt routine in each vector table. Table 1.7 shows the interrupts assigned to the fixed vector tables and addresses of vector tables.

- Variable vector tables The addresses in the variable vector table can be modified, according to the user’s settings. Indicate the first address using the interrupt table register (INTB). The 256-byte area subsequent to the address the INTB indicates becomes the area for the variable vector tables. One vector table comprises four bytes. Set the first address of the interrupt routine in each vector table. Table 1.8 shows the interrupts assigned to the variable vector tables and addresses of vector tables.
SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER Interrupts Interrupt Control Descriptions are given here regarding how to enable or disable maskable interrupts and how to set the priority to be accepted. What is described here does not apply to non-maskable interrupts. Enable or disable a maskable interrupt using the interrupt enable flag (I flag), interrupt priority level select bit, and processor interrupt priority level (IPL). Whether an interrupt request is present or absent is indi- cated by the interrupt request bit. The interrupt request bit and the interrupt priority level selection bit are located in the interrupt control register of each interrupt. Also, the interrupt enable flag (I flag) and the IPL are located in the flag register (FLG). Figure 1.24 shows the interrupt control registers.

SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER Interrupts Interrupt Enable Flag The interrupt enable flag (I flag) controls the enabling and disabling of maskable interrupts. Setting this flag to “1” enables all maskable interrupts; setting it to “0” disables all maskable interrupts. This flag is set to “0” after reset. Interrupt Request Bit The interrupt request bit is set to "1" by hardware when an interrupt is requested. After the interrupt is accepted and jumps to the corresponding interrupt vector, the request bit is set to "0" by hardware. The interrupt request bit can also be set to "0" by software. (Do not set this bit to "1"). Interrupt Priority Level Select Bit and Processor Interrupt Priority Level (IPL) Set the interrupt priority level using the interrupt priority level select bit, which is one of the component bits of the interrupt control register. When an interrupt request occurs, the interrupt priority level is compared with the IPL. The interrupt is enabled only when the priority level of the interrupt is higher than the IPL. Therefore, setting the interrupt priority level to “0” disables the interrupt. Table 1.9 shows the settings of interrupt priority levels and Table 1.10 shows the interrupt levels enabled, according to the consist of the IPL. The following are conditions under which an interrupt is accepted:
- interrupt enable flag (I flag) = 1
- interrupt request bit = 1
- interrupt priority level > IPL The interrupt enable flag (I flag), the interrupt request bit, the interrupt priority select bit, and the IPL are independent, and they are not affected by one another.

SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER Interrupts Changing the Interrupt Control Register < Program examples > The program examples are described as follow: Example 1: INT_SWITCH1: FCLR I ; Disable interrupts. AND.B #00h, 0055h ; Clear TA0IC int. priority level and int. request bit. NOP ; Four NOP instructions are required when using HOLD function. NOP FSET I ; Enable interrupts. Example 2: INT_SWITCH2: FCLR I ; Disable interrupts. AND.B #00h, 0055h ; Clear TA0IC int. priority level and int. request bit. MOV.W MEM, R0 ; Dummy read. FSET I ; Enable interrupts. Example 3: INT_SWITCH3: PUSHC FLG ; Push Flag register onto stack FCLR I ; Disable interrupts. AND.B #00h, 0055h ; Clear TA0IC int. priority level and int. request bit. POPC FLG ; Enable interrupts. The reason why two NOP instructions or dummy read are inserted before FSET I in Examples 1 and 2 is to prevent the interrupt enable flag I from being set before the interrupt control register is rewritten due to effects of the instruction queue. If changing the interrupt control register using an instruction other than the instructions listed hear, and if an interrupt occurs associated with this register during execution of the instruction, there can be instances in which the interrupt request bit is not set. To avoid this problem, use one of the instruc- tions given below to change the register. Following instructions: AND, OR, BCLR or BSET
SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER Interrupts Interrupt Sequence An interrupt sequence — what are performed over a period from the instant an interrupt is accepted to the instant the interrupt routine is executed — is described here. If an interrupt occurs during execution of an instruction, the processor determines its priority when the execution of the instruction is completed, and transfers control to the interrupt sequence from the next cycle. If an interrupt occurs during execution of either the SMOVB, SMOVF, SSTR or RMPA instruction, the processor temporarily suspends the instruction being executed, and transfers control to the interrupt sequence. In the interrupt sequence, the processor carries out the following in sequence given: (1) CPU gets the interrupt information (the interrupt number and interrupt request level) by reading address 00000 16. After this, the corresponding interrupt request bit becomes "0". (2) Saves the content of the flag register (FLG) as it was immediately before the start of interrupt sequence in the temporary register (Note) within the CPU. (3) Sets the interrupt enable flag (I flag), the debug flag (D flag), and the stack pointer select flag (U flag) to “0” (the U flag, however, does not change if the INT instruction, in software interrupt numbers 32 through 63, is executed). (4) Saves the content of the temporary register (Note) within the CPU in the stack area. (5) Saves the content of the program counter (PC) in the stack area. (6) Sets the interrupt priority level of the accepted instruction in the IPL. Interrupt Response Time 'Interrupt response time' is the period between the instant an interrupt occurs and the instant the first instruction within the interrupt routine has been executed. This time comprises the period from the occurrence of an interrupt to the completion of the instruction under execution at that moment (a) and the time required for executing the interrupt sequence (b). Figure 1.25 shows the interrupt response time. Instruction Interrupt sequence Instruction in interrupt routine Time Interrupt response time (a) (b) Interrupt request acknowledgedInterrupt request generated (a) Time from interrupt request is generated to when the instruction then under execution is completed. (b) Time in which the instruction sequence is executed. Figure 1.25. Interrupt response time After the interrupt sequence is completed, the processor resumes executing instructions from the first address of the interrupt routine. Note: This register cannot be utilized by the user.
SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER Interrupts Interrupt sources without priority levels Value set in the IPL Watchdog timer Other Not changed Variation of IPL when Interrupt Request is Accepted If an interrupt request is accepted, the interrupt priority level of the accepted interrupt is set in the IPL. If an interrupt request, that does not have an interrupt priority level, is accepted, one of the values shown in Table 1.12 is set in the IPL. Table 1.12. Relationship between interrupts without interrupt priority levels and IPL Table 1.11. Time required for executing the interrupt sequence Reset Time (a) is dependent on the instruction under execution. Thirty cycles is the maximum required for the DIVX instruction (without wait). Time (b) is as shown in Table 1.11. Note 1: Add 2 cycles in the case of a DBC interrupt; add 1 cycle in the case either of an address match interrupt or of a single-step interrupt.

SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER Interrupts Saving Registers In the interrupt sequence, only the contents of the flag register (FLG) and that of the program counter (PC) are saved in the stack area. First, the processor saves the 4 high-order bits of the program counter, and 4 high-order bits and 8 low- order bits of the FLG register, 16 bits in total, in the stack area, then saves 16 low-order bits of the program counter. Figure 1.27 shows the state of the stack as it was before the acceptance of the interrupt request, and the state the stack after the acceptance of the interrupt request. Save other necessary registers at the beginning of the interrupt routine using software. Using the PUSHM instruction alone can save all the registers except the stack pointer (SP). Figure 1.27.

SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER Interrupts Figure 1.28. Operation of saving registers The operation of saving registers carried out in the interrupt sequence is dependent on whether the content of the stack pointer (Note), at the time of acceptance of an interrupt request, is even or odd. If the content of the stack pointer (Note) is even, the content of the flag register (FLG) and the content of the program counter (PC) are saved, 16 bits at a time. If odd, their contents are saved in two steps, 8 bits at a time. Figure 1.28 shows the operation of the saving registers. Note: Stack pointer indicated by U flag.

SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER Interrupts Key Input Interrupt Key Input Interrupt If the direction register of any of P00 to P07 is set for input and a falling edge is input to that port, a key input interrupt is generated. A key input interrupt can also be used as a key-on wakeup function for cancelling the wait mode or stop mode. Figure 1.31 shows the block diagram of the key input interrupt. Note that if an “L” level is input to any pin that has not been disabled for input, inputs to the other pins are not detected as an interrupt. Figure 1.31.

SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER Interrupts Precautions for Interrupts (1) Reading address 0000016
- When maskable interrupt is occurred, CPU read the interrupt information (the interrupt number and interrupt request level) in the interrupt sequence. The interrupt request bit of the certain interrupt written in address 0000016 will then be set to “0”. Reading address 0000016 by software sets enabled highest priority interrupt source request bit to “0”. Though the interrupt is generated, the interrupt routine may not be executed. Do not read address 00000 16 by software. (2) Setting the stack pointer
- The value of the stack pointer immediately after reset is initialized to 000016. Accepting an interrupt before setting a value in the stack pointer may become a factor of runaway. Be sure to set a value in the stack pointer before accepting an interrupt. Concerning the first instruction immediately after reset, generating any interrupts is prohibited. (3) External interrupt
- Either an “L” level or an “H” level of at least 250 ns width is necessary for the signal input to pins INT0 and INT1 regardless of the CPU operation clock.
- When changing a polarity of pins INT0 and INT1, the interrupt request bit may become "1". Clear the interrupt request bit after changing the polarity. Figure 1.33 shows the switching condition of INT inter- rupt request. Figure 1.33. Switching condition of INT interrupt request (4) Changing interrupt control register See "Changing Interrupt Control Register". Set the interrupt priority level to level 0 (Disable INTi interrupt) Set the polarity select bit Clear the interrupt request bit to “0” Set the interrupt priority level to level 1 to 7 (Enable the accepting of INTi interrupt request) Clear the interrupt enable flag to “0” (Disable interrupt) Set the interrupt enable flag to “1” (Enable interrupt)

- To start reception, the following requirements must be met: - Receive enable bit (bit 2 at addresses 03A516, 03AD16) = “1” - Start bit detection
- When transmitting - Transmit interrupt cause select bits (bits 0,1 at address 03B016) = “0”: Interrupts requested when data transfer from UARTi transfer buffer register to UARTi transmit register is completed - Transmit interrupt cause select bits (bits 0, 1 at address 03B016) = “1”: Interrupts requested when data transmission from UARTi transfer register is completed
- When receiving - Interrupts requested when data transfer from UARTi receive register to UARTi receive buffer register is completed
- Overrun error (Note 3) This error occurs when the next data is ready before contents of UARTi receive buffer register are read out
- Framing error This error occurs when the number of stop bits set is not detected
- Parity error This error occurs when if parity is enabled, the number of 1’s in parity and character bits does not match the number of 1’s set

- With sample and hold function 8-bit resolution: 28 fAD cycles, 10-bit resolution: 33 fAD cycles A-D Converter The A-D converter consists of one 10-bit successive approximation A-D converter circuit with a capacitive coupling amplifier. Pins P6 0 to P67, and P50 to P54 also function as the analog signal input pins. The direction registers of these pins for A-D conversion must therefore be set to input. The Vref connect bit (bit 5 at address 03D7 16) can be used to isolate the resistance ladder of the A-D converter from the reference voltage input pin (VREF ) when the A-D converter is not used. Doing so stops any current flowing into the resistance ladder from VREF , reducing the power dissipation. When using the A-D converter, start A-D conversion only after setting bit 5 of 03D716 to connect VREF . The result of A-D conversion is stored in the A-D registers of the selected pins. When set to 10-bit precision, the low 8 bits are stored in the even addresses and the high 2 bits in the odd addresses. When set to 8-bit precision, the low 8 bits are stored in the even addresses. Table 1.30 shows the performance of the A-D converter. Figure 1.82 shows the block diagram of the A-D converter, and Figures 1.83 and 1.84 show the A-D converter-related registers. Note 1: Does not depend on use of sample and hold function. Note 2: Without sample and hold function, set the fAD frequency to 250kHz min. With the sample and hold function, set the fAD frequency to 1MHz min. Table 1.30. Performance of A-D converter

- Sample and hold Sample and hold is selected by setting bit 0 of the A-D control register 2 (address 03D416) to “1”. When sample and hold is selected, the rate of conversion of each pin increases. As a result, a 28 fAD cycle is achieved with 8-bit resolution and 33 fAD with 10-bit resolution. Sample and hold can be selected in all modes. However, in all modes, be sure to specify before starting A-D conversion whether sample and hold is to be used.

SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER Usage precaution 107 Usage Precaution Timer A (timer mode) (1) Reading the timer A0 register while a count is in progress allows reading, with arbitrary timing, the value of the counter. Reading the timer A0 register with the reload timing gets “FFFF16”. Reading the timer A0 register after setting a value in the timer A0 register with a count halted but before the counter starts counting gets a proper value. Timer A (event counter mode) (1) Reading the timer A0 register while a count is in progress allows reading, with arbitrary timing, the value of the counter. Reading the timer A0 register with the reload timing gets “FFFF16” by under- flow or “000016” by overflow. Reading the timer A0 register after setting a value in the timer A0 register with a count halted but before the counter starts counting gets a proper value. (2) When stop counting in free run type, set timer again. Timer A (one-shot timer mode) (1) Setting the count start flag to “0” while a count is in progress causes as follows:
- The counter stops counting and a content of reload register is reloaded.
- The TA0 OUT pin outputs “L” level.
- The interrupt request generated and the timer A0 interrupt request bit goes to “1”. (2) The timer A0 interrupt request bit goes to “1” if the timer's operation mode is set using any of the following procedures:
- Selecting one-shot timer mode after reset.
- Changing operation mode from timer mode to one-shot timer mode.
- Changing operation mode from event counter mode to one-shot timer mode. Therefore, to use timer A0 interrupt (interrupt request bit), set timer A0 interrupt request bit to “0” after the above listed changes have been made. Timer A (pulse width modulation mode) (1) The timer A0 interrupt request bit becomes “1” if setting operation mode of the timer in compliance with any of the following procedures:
- Selecting PWM mode after reset.
- Changing operation mode from timer mode to PWM mode.
- Changing operation mode from event counter mode to PWM mode. Therefore, to use timer A0 interrupt (interrupt request bit), set timer A0 interrupt request bit to “0” after the above listed changes have been made. (2) Setting the count start flag to “0” while PWM pulses are being output causes the counter to stop counting. If the TA0 OUT pin is outputting an “H” level in this instance, the output level goes to “L”, and the timer A0 interrupt request bit goes to “1”. If the TA0OUT pin is outputting an “L” level in this instance, the level does not change, and the timer A0 interrupt request bit does not becomes “1”.
SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER Usage precaution 108 Timer B (timer mode, event counter mode) (1) Reading the timer Bi register while a count is in progress allows reading , with arbitrary timing, the value of the counter. Reading the timer Bi register with the reload timing gets “FFFF16”. Reading the timer Bi register after setting a value in the timer Bi register with a count halted but before the counter starts counting gets a proper value. Timer B (pulse period/pulse width measurement mode) (1) If changing the measurement mode select bit is set after a count is started, the timer Bi interrupt request bit goes to “1”. (2) When the first effective edge is input after a count is started, an indeterminate value is transferred to the reload register. At this time, timer Bi interrupt request is not generated. Timer X (timer mode) (1) Reading the timer Xi register while a count is in progress allows reading, with arbitrary timing, the value of the counter. Reading the timer Xi register with the reload timing gets “FFFF16”. Reading the timer A0 register after setting a value in the timer Xi register with a count halted but before the counter starts counting gets a proper value. Timer X (event counter mode) (1) Reading the timer Xi register while a count is in progress allows reading, with arbitrary timing, the value of the counter. Reading the timer Xi register with the reload timing gets “FFFF16” by underflow or “000016” by overflow. Reading the timer Xi register after setting a value in the timer Xi register with a count halted but before the counter starts counting gets a proper value. (2) When stop counting in free run type, set timer again. Timer X (one-shot timer mode) (1) Setting the count start flag to “0” while a count is in progress causes as follows:
- The counter stops counting and a content of reload register is reloaded.
- The TXi INOUT pin outputs “L” level.
- The interrupt request generated and the timer Xi interrupt request bit goes to “1”. (2) The timer Xi interrupt request bit goes to “1” if the timer's operation mode is set using any of the following procedures:
- Selecting one-shot timer mode after reset.
- Changing operation mode from timer mode to one-shot timer mode.
- Changing operation mode from event counter mode to one-shot timer mode. Therefore, to use timer Xi interrupt (interrupt request bit), set timer Xi interrupt request bit to “0” after the above listed changes have been made.
SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER Usage precaution 109 Timer X (pulse width modulation mode) (1) The timer Xi interrupt request bit becomes “1” if setting operation mode of the timer in compliance with any of the following procedures:
- Selecting PWM mode after reset.
- Changing operation mode from timer mode to PWM mode.
- Changing operation mode from event counter mode to PWM mode. Therefore, to use timer Xi interrupt (interrupt request bit), set timer Xi interrupt request bit to “0” after the above listed changes have been made. (2) Setting the count start flag to “0” while PWM pulses are being output causes the counter to stop counting. If the TXi INOUT pin is outputting an “H” level in this instance, the output level goes to “L”, and the timer Xi interrupt request bit goes to “1”. If the TXiINOUT pin is outputting an “L” level in this instance, the level does not change, and the timer Xi interrupt request bit does not becomes “1”. Timer X (pulse period/pulse width measurement mode) (1) If changing the measurement mode select bit is set after a count is started, the timer Xi interrupt request bit goes to “1”. (2) When the first effective edge is input after a count is started, an indeterminate value is transferred to the reload register. At this time, timer Xi interrupt request is not generated. A-D Converter (1) Write to each bit (except bit 6) of A-D control register 0, to each bit of A-D control register 1, and to bit 0 of A-D control register 2 when A-D conversion is stopped (before a trigger occurs). In particular, when the Vref connection bit is changed from “0” to “1”, start A-D conversion after an elapse of 1 ms or longer. (2) When changing A-D operation mode, select analog input pin again. (3) Using one-shot mode or single sweep mode Read the correspondence A-D register after confirming A-D conversion is finished. (It is known by A- D conversion interrupt request bit.) (4) Using repeat mode, repeat sweep mode 0 or repeat sweep mode 1 Use the undivided main clock as the internal CPU clock. Stop Mode and Wait Mode (1) When returning from stop mode by hardware reset, RESET pin must be set to “L” level until main clock oscillation is stabilized. (2) When shifting to WAIT mode or STOP mode, the program stops after reading 8 bytes from the WAIT instruction and the instruction that sets all clock stop bits to “1” in the instruction queue. Therefore, insert a minimum of 8 NOPs after the WAIT instruction and the instruction that sets all clock stop bits to “1”.
SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER Usage precaution 110 Interrupts (1) Reading address 0000016
- When maskable interrupt is occurred, CPU read the interrupt information (the interrupt number and interrupt request level) in the interrupt sequence. The interrupt request bit of the certain interrupt written in address 0000016 will then be set to “0”. Reading address 0000016 by software sets enabled highest priority interrupt source request bit to “0”. Though the interrupt is generated, the interrupt routine may not be executed. Do not read address 00000 16 by software. (2) Setting the stack pointer
- The value of the stack pointer immediately after reset is initialized to 000016. Accepting an inter- rupt before setting a value in the stack pointer may become a factor of runaway. Be sure to set a value in the stack pointer before accepting an interrupt. Concerning the first instruction immediately after reset, generating any interrupt is prohibited. (3) External interrupt
- When changing a polarity of pins INT0 and INT1, the interrupt request bit may become "1". Clear the interrupt request bit after changing the polarity. (4) Changing interrupt control register See "Changing Interrupt Control Register".

SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER Preliminary 126 Flash Memory The M30201 (flash memory version) contains the NOR type of flash memory that requires a high-voltage VPP power supply for program/erase operations, in addition to the VCC power supply for device operation. For this flash memory, three flash memory modes are available in which to read, program, and erase: parallel I/O and standard serial I/O modes in which the flash memory can be manipulated using a program- mer and a CPU rewrite mode in which the flash memory can be manipulated by the Central Processing Unit (CPU). Each mode is detailed in the pages to follow. In addition to the ordinary user ROM area to store a microcomputer operation control program, the flash memory has a boot ROM area that is used to store a program to control rewriting in CPU rewrite and standard serial I/O modes. This boot ROM area has had a standard serial I/O mode control program stored in it when shipped from the factory. However, the user can write a rewrite control program in this area that suits the user’s application system. This boot ROM area can be rewritten in only parallel I/O mode. Figure AA-3.

SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER CPU Rewrite Mode Preliminary 127 CPU Rewrite Mode In CPU rewrite mode, the on-chip flash memory can be operated on (read, program, or erase) under control of the Central Processing Unit (CPU). In CPU rewrite mode, the flash memory can be operated on by reading or writing to the flash memory control register and flash command register. Figure BB-1, Figure BB- 2 show the flash memory control register, and flash command register respectively. Also, in CPU rewrite mode, the CNV SS pin is used as the VPP power supply pin. Apply the power supply voltage, VPP H, from an external source to this pin. In CPU rewrite mode, only the user ROM area shown in Figure AA-3 can be rewritten; the boot ROM area cannot be rewritten. Make sure the program and block commands are issued for only the user ROM area. The control program for CPU rewrite mode can be stored in either user ROM or boot ROM area. In the CPU rewrite mode, because the flash memory cannot be read from the CPU, the rewrite control program must be transferred to internal RAM before it can be executed.

SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER CPU Rewrite Mode Preliminary 128 Microcomputer Mode and Boot Mode The control program for CPU rewrite mode must be written into the user ROM or boot ROM area in parallel I/O mode beforehand. (If the control program is written into the boot ROM area, the standard serial I/O mode becomes unusable.) See Figure AA-3 for details about the boot ROM area. Normal microcomputer mode is entered when the microcomputer is reset with pulling CNV SS pin low (VSS ). In this case, the CPU starts operating using the control program in the user ROM area. When the microcomputer is reset by pulling the P52 pin high (VCC ), the CNVSS pin high(VPPH ), the CPU starts operating using the control program in the boot ROM area. This mode is called the “boot” mode. The control program in the boot ROM area can also be used to rewrite the user ROM area. CPU rewrite mode operation procedure The internal flash memory can be operated on to program, read, verify, or erase it while being placed on- board by writing commands from the CPU to the flash memory control register (addresses 03B4 16, 03B516) and flash command register (address 03B616). Note that when in CPU rewrite mode, the boot ROM area cannot be accessed for program, read, verify, or erase operations. Before this can be accom- plished, a CPU write control program must be written into the boot ROM area in parallel input/output mode. The following shows a CPU rewrite mode operation procedure. <Start procedure (Note 1)> (1) Apply VPP H to the CNVSS /VPP pin and VCC to the port P52 pin for reset release. Or the user can jump from the user ROM area to the boot ROM area using the JMP instruction and execute the CPU write control program. In this case, set the CPU write mode select bit of the flash memory control register to “1” before applying V PP H to the CNVSS /VPP pin. (2) After transferring the CPU write control program from the boot ROM area to the internal RAM, jump to this control program in RAM. (The operations described below are controlled by this program.) (3) Set the CPU rewrite mode select bit to “1”. (4) Read the CPU rewrite mode monitor flag to see that the CPU rewrite mode is enabled. (5) Execute operation on the flash memory by writing software commands to the flash command regis- ter. Note 1: In addition to the above, various other operations need to be performed, such as for entering the data to be written to flash memory from an external source (e.g., serial I/O), initializing the ports, and writing to the watchdog timer. <Clearing procedure> (1) Apply VSS to the CNVSS /VPP pin. (2) Set the CPU rewrite mode select bit to “0”.
SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER CPU Rewrite Mode Preliminary 129 Precautions on CPU Rewrite Mode Described below are the precautions to be observed when rewriting the flash memory in CPU rewrite mode. (1) Operation speed During erase/program mode, set BCLK to one of the following frequencies by changing the divide ratio:
5 MHz or less when wait bit (bit 7 at address 0005
16) = 0 (without internal access wait state)
10 MHz or less when wait bit (bit 7 at address 000516) = 1 (with internal access wait state)
(2) Instructions inhibited against use The instructions listed below cannot be used during CPU rewrite mode because they refer to the internal data of the flash memory: UND instruction, INTO instruction, JMPS instruction, JSRS instruction, and BRK instruction (3) Interrupts inhibited against use No interrupts can be used that look up the fixed vector table in the flash memory area. Maskable interrupts may be used by setting the interrupt vector table in a location outside the flash memory area.

When CPU rewrite mode is enabled, write software commands to the flash command register to specify the operation to erase or program. The content of each software command is explained below. Table BB-1. List of Software Commands (CPU Rewrite Mode) Read Command (00 16) The read mode is entered by writing the command code “0016” to the flash command register in the first bus cycle. When an address to be read is input in one of the bus cycles that follow, the content of the specified address is read out at the data bus (D 0–D 7), 8 bits at a time. The read mode is retained intact until another command is written. After reset and after the reset command is executed, the read mode is set. Program Command (40 16) The program mode is entered by writing the command code “4016” to the flash command register in the first bus cycle. When the user execute an instruction to write byte data to the desired address (e.g., STE instruction) in the second bus cycle, the flash memory control circuit executes the program op- eration. The program operation requires approximately 20 ms. Wait for 20 ms or more before the user go to the next processing. During program operation, the watchdog timer remains idle, with the value “7FFF 16” set in it. Note 1: The write operation is not completed immediately by writing a program command once. The user must always execute a program-verify command after each program command executed. And if verification fails, the user need to execute the program command repeatedly until the verification passes. See Figure 1.BB.3 for an example of a programming flowchart.
SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER CPU Rewrite Mode Preliminary 131 Program-verify command (C016) The program-verify mode is entered by writing the command code “C016” to the flash command register in the first bus cycle. When the user execute an instruction (e.g., LDE instruction) to read byte data from the address to be verified (the previously programmed address) in the second bus cycle, the content that has actually been written to the address is read out from the memory. The CPU compares this read data with the data that it previously wrote to the address using the program command. If the compared data do not match, the user need to execute the program and program-verify operations one more time. Erase command (20 16 + 2016) The flash memory control circuit executes an erase operation by writing command code “2016” to the flash command register in the first bus cycle and the same command code to the flash command register again in the second bus cycle. The erase operation requires approximately 20 ms. Wait for 20 ms or more before the user go to the next processing. Before this erase command can be performed, all memory locations to be erased must have had data “00 16” written to by using the program and program-verify commands. During erase operation, the watchdog timer remains idle, with the value “7FFF16 set in it. Note 1: The erase operation is not completed immediately by writing an erase command once. The user must always execute an erase-verify command after each erase command executed. And if verification fails, the user need to execute the erase command repeatedly until the verification passes. See Figure BB-3 for an example of an erase flowchart. Erase-verify command (A0 16) The erase-verify mode is entered by writing the command code “A016” to the flash command register in the first bus cycle. When the user execute an instruction to read byte data from the address to be verified (e.g., LDE instruction) in the second bus cycle, the content of the address is read out. The CPU must sequentially erase-verify memory contents one address at a time, over the entire area erased. If any address is encountered whose content is not “FF 16” (not erased), the CPU must stop erase-verify at that point and execute erase and erase-verify operations one more time. Note 1: If any unerased memory location is encountered during erase-verify operation, be sure to execute erase and erase-verify operations one more time. In this case, however, the user does not need to write data “00 16” to memory before erasing.

After writing command code “40 16” or “2016” twice to the flash command register, write command code “FF16” to the flash command register in the first bus cycle and the same command code to the flash command register again in the second bus cycle. The program command or erase command is disabled, with the flash memory placed in read mode.

In the boot ROM area, an erase block operation is applied to only one 4 K byte block. The boot ROM area has had a standard serial I/O mode control program stored in it when shipped from the Mitsubishi factory. Therefore, using the device in standard serial input/output mode, the user does not need to write to the boot ROM area. Functional Outline (Parallel I/O Mode) In parallel I/O mode, bus operation modes—Read, Output Disable, Standby, and Write—are selected by the status of the CE, OE, WE, VRFY , and CNVSS input pins. The contents of erase, program, and other operations are selected by writing a software command. The data in memory can only be read out by a read after software command input. Program and erase operations are controlled using software commands. Table CC-3. Relationship between control signals and bus operation modes
Appendix Parallel I/O Mode Preliminary Under development Mitsubishi microcomputers M30201 Group SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER 138 The following explains about bus operation modes, software commands, and status register. Bus Operation Modes Read-only mode is entered by applying VPPH to the CNVSS pin and a low voltage to the VRFY pin. Read-only mode has three states: Read, Output Disable, and Standby which are selected by setting the CE, OE, and WE pins high or low. Read-write mode is entered by applying V PPH to the CNVSS pin and a high voltage to the VRFY pin. Read-write mode has four states: Read, Output Disable, Standby, and Write which are selected by setting the CE, OE, and WE pins high or low. Read The Read mode is entered by pulling the WE pin high when the CE and OE pins are low. In Read mode, the data corresponding to each software command entered is output from the data I/O pins D 0–D 7. Output Disable The Output Disable mode is entered by pulling the CE pin low and the WE and OE pins high. Also, the data I/O pins are placed in the high-impedance state. Standby The Standby mode is entered by driving the CE pin high. Also, the data I/O pins are placed in the high-impedance state. Write The Write mode is entered by applying VPPH to the CNVSS pin and a high voltage to the VRFY pin and then pulling the WE pin low when the CE pin is low and OE pin is high. In this mode, the device accepts the software commands or write data entered from the data I/O pins. A program, erase, or some other operation is initiated depending on the content of the software command entered here. The input data such as address is latched at the falling edge of WE pin. The input data such as software command is latched at the rising edge of WE pin.

By entering a software command from the data I/O pins (D0–D 7) in Write mode, specify the content of the operation, such as erase or program operation, to be performed. The following explains the content of each software command. Table CC-4. Software command list (parallel I/O mode) Read Command (00 16) The read mode is entered by writing the command code “0016” in the first bus cycle. When an address to be read is input in one of the bus cycles that follow, the content of the specified address is read out at the data I/O pins (D 0–D 7). The read mode is retained intact until another command is written. After reset and after the reset command is executed, the read mode is set. Program Command (40 16) The program mode is entered by writing the command code “4016” in the first bus cycle. When an address and data to be program is write in the second bus cycle, the flash memory control circuit executes the program operation. The program operation requires approximately 20 ms. Wait for 20 ms or more before the user go to the next processing. Note 1: The write operation is not completed immediately by writing a program command once. The user must always execute a program-verify command after each program command executed. And if verification fails, the user need to execute the program command repeatedly until the verification passes. See Figure CC-4 for an example of a programming flowchart.
Appendix Parallel I/O Mode Preliminary Under development Mitsubishi microcomputers M30201 Group SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER 140 Program-verify command (C016) The program-verify mode is entered by writing the command code “C016” in the first bus cycle and the verify data is output from the data I/O pins (D0–D 7) in the second bus cycle. Erase command (2016 + 2016) The flash memory control circuit executes an erase operation by writing command code “2016” in the first bus cycle and the same command code again in the second bus cycle. The erase operation requires approximately 20 ms. Wait for 20 ms or more before the user go to the next processing. Before this erase command can be performed, all memory locations to be erased must have had data “00 16” written to by using the program and program-verify commands. Note 1: The erase operation is not completed immediately by writing an erase command once. The user must always execute an erase-verify command after each erase command executed. And if verification fails, the user need to execute the erase command repeatedly until the verification passes. See Figure CC-4 for an example of an erase flowchart. Erase-verify command (A0 16) The erase-verify mode is entered by writing the command code “A016” in the first bus cycle and the verify data is output from the data I/O pins (D0–D 7) in the second bus cycle. Note 1: If any unerased memory location is encountered during erase-verify operation, be sure to execute erase and erase-verify operations one more time. In this case, however, the user does not need to write data “00 16” to memory before erasing.

Appendix Parallel I/O Mode Preliminary Under development Mitsubishi microcomputers M30201 Group SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER 142 Figure CC-5. Protect control address Protect function In parallel I/O mode, the internal flash memory has the “protect function” available. This function protects the flash memory contents from being read or rewritten easily. Depending on the content at the protect control address (FFFFF 16) in parallel I/O mode, this function inhibits the flash memory contents against read or modification. The protect control address (FFFFF16) is shown in Figure CC-5 . (This address exists in the user ROM area.) The protect function is enabled by setting one of the two protect set bits to “0”, so that the internal flash memory contents are inhibited against read or modification. The protect function is disabled by setting both of the two protect reset bits to “00”, so that the internal flash memory contents can be read or modified. Once the protect function is set, the user cannot change settings of the protect clear bits while in parallel I/O mode. Settings of the protect reset bits can only be changed in CPU rewrite mode.

SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER Appendix Standard Serial I/O Mode Preliminary 146 Standard Serial I/O Mode The standard serial I/O mode serially inputs and outputs the software commands, addresses and data necessary for operating (read, program, erase, etc.) the internal flash memory. It uses a purpose-specific serial programmer. The standard serial I/O mode differs from the parallel I/O mode in that the CPU controls operations like rewriting (uses the CPU rewrite mode) in the flash memory or serial input for rewriting data. The standard serial I/O mode is started by clearing the reset with V PPH at the CNVss pin. (For the normal microprocessor mode, set CNVss to “L”.) This control program is written in the boot ROM area when shipped from Mitsubishi Electric. Therefore, if the boot ROM area is rewritten in the parallel I/O mode, the standard serial I/O mode cannot be used. Figures DD-1 and DD-2 show the pin connections for the standard serial I/O mode. Serial data I/O uses three UART0 pins: CLK 0, RxD0, and TxD0 and port P53 (BUSY). The CLK0 pin is the transfer clock input pin and it transfers the external transfer clock. The TxD0 pin outputs the CMOS signal. The P53 (BUSY) pin outputs an “L” level when reception setup ends and an “H” level when the reception operation starts. Transmission and reception data is transferred serially in 8-byte blocks. In the standard serial I/O mode, only the user ROM area shown in Figure CC-1 can be rewritten, the boot ROM area cannot. The standard serial I/O mode has a 7-byte ID code. When the flash memory is not blank and the ID code does not match the content of the flash memory, the command sent from the programmer is not accepted. Function Overview (Standard Serial I/O Mode) In the standard serial I/O mode, software commands, addresses and data are input and output between the flash memory and an external device (serial programmer, etc.) using a clock synchronized serial I/O (UART0) and P5 3. In reception, the software commands, addresses and program data are synchronized with the rise of the transfer clock input to the CLK0 pin and input into the flash memory via the RxD0 pin. In transmission, the read data and status are synchronized with the fall of the transfer clock and output to the outside from the TxD 0 pin. The TxD1 pin is CMOS output. Transmission is in 8-bit blocks and LSB first. When busy, either during transmission or reception, or while executing an erase operation or program, the P5 3 (BUSY) pin is “H” level. Accordingly, do not start the next transmission until the P53 (BUSY) pin is “L” level. Also, data in memory and the status register can be read after inputting a software command. It is pos- sible to check flash memory operating status or whether a program or erase operation ended success- fully or in error by reading the status register. Software commands and the status register are explained here following.

SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER Appendix Standard Serial I/O Mode Preliminary 154 Status Register (SRD) The status register indicates operating status of the flash memory and status such as whether an erase operation or a program ended successfully or in error. It can be read by writing the read status register command (70 16). Also, the status register is cleared by writing the clear status register command (5016). Table DD-2 gives the definition of each status register bit. After clearing the reset, the status register outputs “80 16”. Table DD-2. Status register (SRD) Status Bit (SR7) The status bit indicates the operating status of the flash memory. When power is turned on, “1” (ready) is set for it. The bit is set to “0” (busy) during an auto write or auto erase operation, but it is set back to “1” when the operation ends. Erase Bit (SR5) The erase bit reports the operating status of the auto erase operation. If an erase error occurs, it is set to “1”. When the erase status is cleared, it is set to “0”. Program Bit (SR4) The program bit reports the operating status of the auto write operation. If a write error occurs, it is set to “1”. When the program status is cleared, it is set to “0”.
