SINGLE-CHIP 4-BIT CMOS MICROCOMPUTER MITSUBISHI MICROCOMPUTERS Notes 1: Pins except above have just single function. 2: The input of D6, D7, P20–P2 2, CMP0-, CMP0+, CMP1-, CMP1+ and the input/output of P30, P31, P40–P43 can be used even when CNTR0, CNTR1, SCK , SOUT , SIN, INT0, INT1, and AIN0–AIN7 are selected. 3: The 4513 Group does not have P40/AIN4–P43/AIN7. Notes 1: After system is released from reset, port P5 is in an input mode (di- rection register FR0 = 00002) 2: When the P00–P0 3 and P10–P1 3 are connected to VSS , turn off their pull-up transistors (register PU0i=“0”) and also invalidate the key-on wakeup functions (register K0i=“0”) by software. When these pins are connected to VSS while the key-on wakeup func- tions are left valid, the system fails to return from RAM back-up state. When these pins are open, turn on their pull-up transistors (register PU0i=“1”) by software, or set the output latch to “0.” Be sure to select the key-on wakeup functions and the pull-up functions with every two pins. If only one of the two pins for the key-on wakeup function is used, turn on their pull-up transistors by software and also disconnect the other pin. (i = 0, 1, 2, or 3.) (Note when the output latch is set to “0” and pins are open) G After system is released from reset, port is in a high-impedance state un- til it is set the output latch to “0” by software. Accordingly, the voltage level of pins is undefined and the excess of the supply current may occur while the port is in a high-impedance state. G To set the output latch periodically by software is recommended because value of output latch may change by noise or a program run away (caused by noise). (Note when connecting to V SS and VDD ) G Connect the unused pins to VSS and VDD using the thickest wire at the shortest distance against noise.

The value of A 0 is stored in carry flag CY with the RAR instruction (Fig- ure 2). Carry flag CY can be set to “1” with the SC instruction and cleared to “0” with the RC instruction. (3) Registers B and E Register B is a 4-bit register used for temporary storage of 4-bit data, and for 8-bit data transfer together with register A. Register E is an 8-bit register. It can be used for 8-bit data transfer with register B used as the high-order 4 bits and register A as the low-order 4 bits (Figure 3). (4) Register D Register D is a 3-bit register. It is used to store a 7-bit ROM address together with register A and is used as a pointer within the specified page when the TABP p, BLA p, or BMLA p instruction is executed (Figure 4).

SINGLE-CHIP 4-BIT CMOS MICROCOMPUTER MITSUBISHI MICROCOMPUTERS (5) Stack registers (SKS) and stack pointer (SP) Stack registers (SKs) are used to temporarily store the contents of program counter (PC) just before branching until returning to the original routine when;
- branching to an interrupt service routine (referred to as an inter- rupt service routine),
- performing a subroutine call, or
- executing the table reference instruction (TABP p). Stack registers (SKs) are eight identical registers, so that subrou- tines can be nested up to 8 levels. However, one of stack registers is used respectively when using an interrupt service routine and when executing a table reference instruction. Accordingly, be care- ful not to over the stack when performing these operations together. The contents of registers SKs are destroyed when 8 lev- els are exceeded. The register SK nesting level is pointed automatically by 3-bit stack pointer (SP). The contents of the stack pointer (SP) can be transferred to register A with the TASP instruction. Figure 5 shows the stack registers (SKs) structure. Figure 6 shows the example of operation at subroutine call. (6) Interrupt stack register (SDP) Interrupt stack register (SDP) is a 1-stage register. When an inter- rupt occurs, this register (SDP) is used to temporarily store the contents of data pointer, carry flag, skip flag, register A, and regis- ter B just before an interrupt until returning to the original routine. Unlike the stack registers (SKs), this register (SDP) is not used when executing the subroutine call instruction and the table refer- ence instruction. (7) Skip flag Skip flag controls skip decision for the conditional skip instructions and continuous described skip instructions. When an interrupt oc- curs, the contents of skip flag is stored automatically in the interrupt stack register (SDP) and the skip condition is retained.

It points “0” by executing the first BM instruction, and the contents of program counter is stored in SK0. When the BM instruction is executed after eight stack registers are used ((SP) = 7), (SP) = 0 and the contents of SK0 is destroyed.
SINGLE-CHIP 4-BIT CMOS MICROCOMPUTER MITSUBISHI MICROCOMPUTERS (8) Program counter (PC) Program counter (PC) is used to specify a ROM address (page and address). It determines a sequence in which instructions stored in ROM are read. It is a binary counter that increments the number of instruction bytes each time an instruction is executed. However, the value changes to a specified address when branch instructions, subroutine call instructions, return instructions, or the table refer- ence instruction (TABP p) is executed. Program counter consists of PC H (most significant bit to bit 7) which specifies to a ROM page and PCL (bits 6 to 0) which speci- fies an address within a page. After it reaches the last address (address 127) of a page, it specifies address 0 of the next page (Figure 7). Make sure that the PC H does not specify after the last page of the built-in ROM. (9) Data pointer (DP) Data pointer (DP) is used to specify a RAM address and consists of registers Z, X, and Y . Register Z specifies a RAM file group, reg- ister X specifies a file, and register Y specifies a RAM digit (Figure 8). Register Y is also used to specify the port D bit position. When using port D, set the port D bit position to register Y certainly and execute the SD, RD, or SZD instruction (Figure 9).

ROM is separated every 128 words by the unit of page (addresses 0 to 127). Table 1 shows the ROM size and pages. Fig- ure 10 shows the ROM map of M34514M8/E8.

When an interrupt occurs, the address (interrupt address) corresponding to each interrupt is set in the program counter, and the instruction at the interrupt address is executed. When using an interrupt service routine, write the in- struction generating the branch to that routine at an interrupt address. Page 2 (addresses 0100 16 to 017F16) is the special page for sub- routine calls. Subroutines written in this page can be called from any page with the 1-word instruction (BM). Subroutines extending from page 2 to another page can also be called with the BM in- struction when it starts on page 2. ROM pattern (bits 7 to 0) of all addresses can be used as data ar- eas with the TABP p instruction.

SINGLE-CHIP 4-BIT CMOS MICROCOMPUTER MITSUBISHI MICROCOMPUTERS INTERRUPT FUNCTION The interrupt type is a vectored interrupt branching to an individual address (interrupt address) according to each interrupt source. An interrupt occurs when the following 3 conditions are satisfied.
- An interrupt activated condition is satisfied (request flag = “1”)
- Interrupt enable bit is enabled (“1”)
- Interrupt enable flag is enabled (INTE = “1”) Table 3 shows interrupt sources. (Refer to each interrupt request flag for details of activated conditions.) (1) Interrupt enable flag (INTE) The interrupt enable flag (INTE) controls whether the every inter- rupt enable/disable. Interrupts are enabled when INTE flag is set to “1” with the EI instruction and disabled when INTE flag is cleared to “0” with the DI instruction. When any interrupt occurs, the INTE flag is automatically cleared to “0,” so that other interrupts are disabled until the EI instruction is executed. (2) Interrupt enable bit Use an interrupt enable bit of interrupt control registers V1 and V2 to select the corresponding interrupt or skip instruction. Table 4 shows the interrupt request flag, interrupt enable bit and skip instruction. Table 5 shows the interrupt enable bit function. (3) Interrupt request flag When the activated condition for each interrupt is satisfied, the cor- responding interrupt request flag is set to “1.” Each interrupt request flag is cleared to “0” when either;
- an interrupt occurs, or
- the next instruction is skipped with a skip instruction. Each interrupt request flag is set when the activated condition is satisfied even if the interrupt is disabled by the INTE flag or its in- terrupt enable bit. Once set, the interrupt request flag retains set until a clear condition is satisfied. Accordingly, an interrupt occurs when the interrupt disable state is released while the interrupt request flag is set. If more than one interrupt request flag is set when the interrupt dis- able state is released, the interrupt priority level is as follows shown in Table 3. Table 3 Interrupt sources Activated condition Level change of INT0 pin Level change of INT1 pin Timer 1 underflow Timer 2 underflow Timer 3 underflow Timer 4 underflow Completion of A-D conversion Completion of serial I/O transfer Priority level Interrupt name External 0 interrupt External 1 interrupt Timer 1 interrupt Timer 2 interrupt Timer 3 interrupt Timer 4 interrupt A-D interrupt Serial I/O interrupt Request flag EXF0 EXF1 T1F T2F T3F T4F ADF SIOF Interrupt name External 0 interrupt External 1 interrupt Timer 1 interrupt Timer 2 interrupt Timer 3 interrupt Timer 4 interrupt A-D interrupt Serial I/O interrupt Table 5 Interrupt enable bit function Occurrence of interrupt Enabled Disabled Skip instruction Invalid Valid Interrupt enable bit Interrupt address Address 0 in page 1 Address 2 in page 1 Address 4 in page 1 Address 6 in page 1 Address 8 in page 1 Address A in page 1 Address C in page 1 Address E in page 1 Table 4 Interrupt request flag, interrupt enable bit and skip in- struction Skip instruction SNZ0 SNZ1 SNZT1 SNZT2 SNZT3 SNZT4 SNZAD SNZSI Enable bit V1 0 V11 V1 2 V1 3 V2 0 V2 1 V2 2 V2 3
SINGLE-CHIP 4-BIT CMOS MICROCOMPUTER MITSUBISHI MICROCOMPUTERS (4) Internal state during an interrupt The internal state of the microcomputer during an interrupt is as follows (Figure 14).
- Program counter (PC) An interrupt address is set in program counter. The address to be executed when returning to the main routine is automatically stored in the stack register (SK).
- Interrupt enable flag (INTE) INTE flag is cleared to “0” so that interrupts are disabled.
- Interrupt request flag Only the request flag for the current interrupt source is cleared to “0.”
- Data pointer, carry flag, skip flag, registers A and B The contents of these registers and flags are stored automati- cally in the interrupt stack register (SDP). (5) Interrupt processing When an interrupt occurs, a program at an interrupt address is ex- ecuted after branching a data store sequence to stack register. Write the branch instruction to an interrupt service routine at an in- terrupt address. Use the RTI instruction to return from an interrupt service routine. Interrupt enabled by executing the EI instruction is performed after executing 1 instruction (just after the next instruction is executed). Accordingly, when the EI instruction is executed just before the RTI instruction, interrupts are enabled after returning the main routine.

- Interrupt control register V2 Interrupt enable bits of timer 3, timer 4, A-D and serial I/O are as- signed to register V2. Set the contents of this register through register A with the TV2A instruction. The TAV2 instruction can be used to transfer the contents of register V2 to register A.

SINGLE-CHIP 4-BIT CMOS MICROCOMPUTER MITSUBISHI MICROCOMPUTERS (7) Interrupt sequence Interrupts only occur when the respective INTE flag, interrupt en- able bits (V10–V1 3 and V20–V2 3), and interrupt request flag are “1.” The interrupt actually occurs 2 to 3 machine cycles after the cycle in which all three conditions are satisfied. The interrupt oc- curs after 3 machine cycles only when the three interrupt condi- tions are satisfied on execution of other than one-cycle instructions (Refer to Figure 16). Fig. 16 Interrupt sequence T1 T2 T3 T1 T2 T3 T1 T2 T3 System clock T1 T2 T3 EXF0, EXF1 T1F, T2F, T3F, T4F, ADF,SIOF INT0, INT1 T1 T2 T3 2 to 3 machine cycles (Notes 2, 3) The program starts from the interrupt address.

An external interrupt request occurs when a valid waveform is input to an interrupt input pin (edge detection). The external interrupts can be controlled with the interrupt control registers I1 and I2.

SINGLE-CHIP 4-BIT CMOS MICROCOMPUTER MITSUBISHI MICROCOMPUTERS (1) External 0 interrupt request flag (EXF0) External 0 interrupt request flag (EXF0) is set to “1” when a valid waveform is input to P30/INT0 pin. The valid waveforms causing the interrupt must be retained at their level for 4 clock cycles or more of the system clock (Refer to Figure 16). The state of EXF0 flag can be examined with the skip instruction (SNZ0). Use the interrupt control register V1 to select the interrupt or the skip instruction. The EXF0 flag is cleared to “0” when an in- terrupt occurs or when the next instruction is skipped with the skip instruction. The P3 0/INT0 pin need not be selected the external interrupt input INT0 function or the normal I/O port P30 function. However, the EXF0 flag is set to “1” when a valid waveform is input even if it is used as an I/O port P30.
- External 0 interrupt activated condition External 0 interrupt activated condition is satisfied when a valid waveform is input to P30/INT0 pin. The valid waveform can be selected from rising waveform, falling waveform or both rising and falling waveforms. An example of how to use the external 0 interrupt is as follows. ➀ Select the valid waveform with the bits 1 and 2 of register I1. ➁ Clear the EXF0 flag to “0” with the SNZ0 instruction. ➂ Set the NOP instruction for the case when a skip is performed with the SNZ0 instruction. ➃ Set both the external 0 interrupt enable bit (V1 0) and the INTE flag to “1.” The external 0 interrupt is now enabled. Now when a valid wave- form is input to the P3 0/INT0 pin, the EXF0 flag is set to “1” and the external 0 interrupt occurs. (2) External 1 interrupt request flag (EXF1) External 1 interrupt request flag (EXF1) is set to “1” when a valid waveform is input to P31/INT1 pin. The valid waveforms causing the interrupt must be retained at their level for 4 clock cycles or more of the system clock (Refer to Figure 16). The state of EXF1 flag can be examined with the skip instruction (SNZ1). Use the interrupt control register V1 to select the interrupt or the skip instruction. The EXF1 flag is cleared to “0” when an in- terrupt occurs or when the next instruction is skipped with the skip instruction. The P3 1/INT1 pin need not be selected the external interrupt input INT1 function or the normal I/O port P31 function. However, the EXF1 flag is set to “1” when a valid waveform is input even if it is used as an I/O port P31.
- External 1 interrupt activated condition External 1 interrupt activated condition is satisfied when a valid waveform is input to P31/INT1 pin. The valid waveform can be selected from rising waveform, falling waveform or both rising and falling waveforms. An example of how to use the external 1 interrupt is as follows. ➀ Select the valid waveform with the bits 1 and 2 of register I2. ➁ Clear the EXF1 flag to “0” with the SNZ1 instruction. ➂ Set the NOP instruction for the case when a skip is performed with the SNZ1 instruction. ➃ Set both the external 1 interrupt enable bit (V1 1) and the INTE flag to “1.” The external 1 interrupt is now enabled. Now when a valid wave- form is input to the P3 1/INT1 pin, the EXF1 flag is set to “1” and the external 1 interrupt occurs.

SINGLE-CHIP 4-BIT CMOS MICROCOMPUTER MITSUBISHI MICROCOMPUTERS TIMERS The 4513/4514 Group has the programmable timers.
- Programmable timer The programmable timer has a reload register and enables the frequency dividing ratio to be set. It is decremented from a setting value n. When it underflows (count to n + 1), a timer interrupt re- quest flag is set to “1,” new data is loaded from the reload register, and count continues (auto-reload function).
- Fixed dividing frequency timer The fixed dividing frequency timer has the fixed frequency divid- ing ratio (n). An interrupt request flag is set to “1” after every n count of a count pulse.

SINGLE-CHIP 4-BIT CMOS MICROCOMPUTER MITSUBISHI MICROCOMPUTERS (1) Timer control registers
- Timer control register W1 Register W1 controls the count operation of timer 1, the selection of count start synchronous circuit, and the frequency dividing ra- tio and count operation of prescaler. Set the contents of this register through register A with the TW1A instruction. The TAW1 instruction can be used to transfer the contents of register W1 to register A.
- Timer control register W2 Register W2 controls the count operation and count source of timer 2. Set the contents of this register through register A with the TW2A instruction. The TAW2 instruction can be used to trans- fer the contents of register W2 to register A.
- Timer control register W3 Register W3 controls the count operation and count source of timer 3 and the selection of count start synchronous circuit. Set the contents of this register through register A with the TW3A in- struction. The TAW3 instruction can be used to transfer the contents of register W3 to register A.
- Timer control register W4 Register W4 controls the count operation and count source of timer 4. Set the contents of this register through register A with the TW4A instruction. The TAW4 instruction can be used to trans- fer the contents of register W4 to register A.
- Timer control register W6 Register W6 controls the D 6/CNTR0 pin and D7/CNTR1 func- tions, the selection and operation of the CNTR0 and CNTR1 output. Set the contents of this register through register A with the TW6A instruction. The TAW6 instruction can be used to trans- fer the contents of register W6 to register A. (2) Precautions Note the following for the use of timers.
- Prescaler Stop the prescaler operation to change its frequency dividing ra- tio.
- Count source Stop timer 1, 2, 3, or 4 counting to change its count source.
- Reading the count value Stop timer 1, 2, 3, or 4 counting and then execute the TAB1, TAB2, TAB3, or TAB4 instruction to read its data.
- Writing to reload registers R1 and R3 When writing data to reload registers R1 or R3 while timer 1 or timer 3 is operating, avoid a timing when timer 1 or timer 3 underflows. (3) Prescaler Prescaler is a frequency divider. Its frequency dividing ratio can be selected. The count source of prescaler is the instruction clock. Use the bit 2 of register W1 to select the prescaler dividing ratio and the bit 3 to start and stop its operation. Prescaler is initialized, and the output signal (ORCLK) stops when the bit 3 of register W1 is cleared to “0.” (4) Timer 1 (interrupt function) Timer 1 is an 8-bit binary down counter with the timer 1 reload reg- ister (R1). Data can be set simultaneously in timer 1 and the reload register (R1) with the T1AB instruction. Data can be written to re- load register (R1) with the TR1AB instruction. When writing data to reload register R1 with the TR1AB instruction, the downcount after the underflow is started from the setting value of reload register R1. Timer 1 starts counting after the following process; ➀ set data in timer 1, and ➁ set the bit 1 of register W1 to “1.” However, P3 0/INT0 pin input can be used as the start trigger for timer 1 count operation by setting the bit 0 of register W1 to “1.” When a value set in timer 1 is n, timer 1 divides the count source signal by n + 1 (n = 0 to 255). Once count is started, when timer 1 underflows (the next count pulse is input after the contents of timer 1 becomes “0”), the timer 1 interrupt request flag (T1F) is set to “1,” new data is loaded from reload register R1, and count continues (auto-reload function). Data can be read from timer 1 with the TAB1 instruction. When reading the data, stop the counter and then execute the TAB1 in- struction. Timer 1 underflow signal divided by 2 can be output from D 6/CNTR0 pin. (5) Timer 2 (interrupt function) Timer 2 is an 8-bit binary down counter with the timer 2 reload reg- ister (R2). Data can be set simultaneously in timer 2 and the reload register (R2) with the T2AB instruction. Timer 2 starts counting after the following process; ➀ set data in timer 2, ➁ select the count source with the bits 0 and 1 of register W2, and ➂ set the bit 3 of register W2 to “1.” When a value set in timer 2 is n, timer 2 divides the count source signal by n + 1 (n = 0 to 255). Once count is started, when timer 2 underflows (the next count pulse is input after the contents of timer 2 becomes “0”), the timer 2 interrupt request flag (T2F) is set to “1,” new data is loaded from reload register R2, and count continues (auto-reload function). Data can be read from timer 2 with the TAB2 instruction. When reading the data, stop the counter and then execute the TAB2 in- struction. The output from D 6/CNTR0 pin by timer 2 underflow signal divided by 2 can be controlled.
SINGLE-CHIP 4-BIT CMOS MICROCOMPUTER MITSUBISHI MICROCOMPUTERS (6) Timer 3 (interrupt function) Timer 3 is an 8-bit binary down counter with the timer 3 reload reg- ister (R3). Data can be set simultaneously in timer 3 and the reload register (R3) with the T3AB instruction. Data can be written to re- load register (R3) with the TR3AB instruction. When writing data to reload register R3 with the TR3AB instruction, the downcount after the underflow is started from the setting value of reload register R3. Timer 3 starts counting after the following process; ➀ set data in timer 3, ➁ select the count source with the bits 0 and 1 of register W3, and ➂ set the bit 3 of register W3 to “1.” However, P3 1/INT1 pin input can be used as the start trigger for timer 3 count operation by setting the bit 2 of register W3 to “1.” When a value set in timer 3 is n, timer 3 divides the count source signal by n + 1 (n = 0 to 255). Once count is started, when timer 3 underflows (the next count pulse is input after the contents of timer 3 becomes “0”), the timer 3 interrupt request flag (T3F) is set to “1,” new data is loaded from reload register R3, and count continues (auto-reload function). Data can be read from timer 3 with the TAB3 instruction. When reading the data, stop the counter and then execute the TAB3 in- struction. Timer 3 underflow signal divided by 2 can be output from D 7/CNTR1 pin. (7) Timer 4 (interrupt function) Timer 4 is an 8-bit binary down counter with the timer 4 reload reg- ister (R4). Data can be set simultaneously in timer 4 and the reload register (R4) with the T4AB instruction. Timer 4 starts counting after the following process; ➀ set data in timer 4, ➁ select the count source with the bits 0 and 1 of register W4, and ➂ set the bit 3 of register W4 to “1.” When a value set in timer 4 is n, timer 4 divides the count source signal by n + 1 (n = 0 to 255). Once count is started, when timer 4 underflows (the next count pulse is input after the contents of timer 4 becomes “0”), the timer 4 interrupt request flag (T4F) is set to “1,” new data is loaded from reload register R4, and count continues (auto-reload function). Data can be read from timer 4 with the TAB4 instruction. When reading the data, stop the counter and then execute the TAB4 in- struction. The output from D 7/CNTR1 pin by timer 4 underflow signal divided by 2 can be controlled. (8) Timer interrupt request flags (T1F, T2F, T3F, and T4F) Each timer interrupt request flag is set to “1” when each timer underflows. The state of these flags can be examined with the skip instructions (SNZT1, SNZT2, SNZT3, and SNZT4). Use the interrupt control registers V1, V2 to select an interrupt or a skip instruction. An interrupt request flag is cleared to “0” when an interrupt occurs or when the next instruction is skipped with a skip instruction. (9) Timer I/O pin (D6/CNTR0, D7/CNTR1) D 6/CNTR0 pin has functions to input the timer 2 count source, and to output the timer 1 and timer 2 underflow signals divided by 2. D7/ CNTR1 pin has functions to input the timer 4 count source, and to output the timer 3 and timer 4 underflow signals divided by 2. The selection of D 6/CNTR0 pin function can be controlled with the bit 0 of register W6. The selection of D7/CNTR1 pin function can be controlled with the bit 2 of register W6. The following signals can be selected for the CNTR0 output signal with the bit 1 of register W6.
- timer 1 underflow signal divided by 2
- the signal of AND operation between timer 1 underflow signal di- vided by 2 and timer 2 underflow signal divide by 2 The following signals can be selected for the CNTR1 output signal with the bit 3 of register W6.
- timer 3 underflow signal divided by 2
- the signal of AND operation between timer 3 underflow signal di- vided by 2 and timer 4 underflow signal divide by 2 Timer 2 counts the rising waveform of CNTR0 input when the CNTR0 input is selected as the count source. Timer 4 counts the rising waveform of CNTR1 input when the CNTR1 input is selected as the count source. (10) Count start synchronous circuit (timer 1 and 3) Each of timer 1 and timer 3 has the count start synchronous circuit which synchronizes P3 0/INT0 pin and P31/INT1 pin, respectively, and can start the timer count operation. Timer 1 count start synchronous circuit function is selected by set- ting the bit 0 of register W1 to “1.” The control by P3 0/INT0 pin input can be performed by setting the bit 0 of register I1 to “1.” The count start synchronous circuit is set by level change (“H ”→ “L” or “L”→ “H ”) of P30/INT0 pin input. This valid waveform is selected by bits 1 (I11) and 2 (I12) of register I1 as follows;
- I11 = “0”: Synchronized with one-sided edge (falling or rising)
- I11 = “1”: Synchronized with both edges (both falling and rising) When register I11=“0” (synchronized with the one-sided edge), the ris- ing or falling waveform can be selected by bit 2 of register I1;
- I12 = “0”: Falling waveform
- I12 = “1”: Rising waveform Timer 3 count start synchronous circuit function is selected by set- ting the bit 2 of register W3 to “1.” The control by P31/INT1 pin input can be performed by setting the bit 0 of register I2 to “1.” The count start synchronous circuit is set by level change (“H ”→ “L” or “L”→ “H ”) of P31/INT1 pin input. This valid waveform is selected by bits 1 (I21) and 2 (I22) of register I2 as follows;
- I21 = “0”: Synchronized with one-sided edge (falling or rising)
- I21 = “1”: Synchronized with both edges (both falling and rising) When register I21=“0” (synchronized with the one-sided edge), the ris- ing or falling waveform can be selected by bit 2 of register I2;
- I22 = “0”: Falling waveform
- I22 = “1”: Rising waveform When timer 1 and timer 3 count start synchronous circuits are used, the count start synchronous circuits are set, the count source is input to each timer by inputting valid waveform to P30/INT0 pin and P31/INT1 pin. Once set, the count start synchronous circuit is cleared by clearing the bit I10 or I20 to “0” or reset.
SINGLE-CHIP 4-BIT CMOS MICROCOMPUTER MITSUBISHI MICROCOMPUTERS WATCHDOG TIMER Watchdog timer provides a method to reset the system when a pro- gram runs wild. Watchdog timer consists of a 16-bit timer (WDT), watchdog timer enable flag (WEF), and watchdog timer flags (WDF1, WDF2). The timer WDT downcounts the instruction clocks as the count source. The underflow signal is generated when the count value reaches “0000 16.” This underflow signal can be used as the timer 2 count source. When the WRST instruction is executed after system is released from reset, the WEF flag is set to “1”. At this time, the watchdog timer starts operating. When the count value of timer WDT reaches “BFFF 16” or “3FFF16,” the WDF1 flag is set to “1.” If the WRST instruction is never ex- ecuted while timer WDT counts 32767, WDF2 flag is set to “1,” and the RESET pin outputs “L” level to reset the microcomputer. Ex- ecute the WRST instruction at each period of 32766 machine cycle or less by software when using watchdog timer to keep the micro- computer operating normally. To prevent the WDT stopping in the event of misoperation, WEF flag is designed not to initialize once the WRST instruction has been executed. Note also that, if the WRST instruction is never ex- ecuted, the watchdog timer does not start. Fig. 20 Watchdog timer function The contents of WEF, WDF1 and WDF2 flags and timer WDT are initialized at the RAM back-up mode. If WDF2 flag is set to “1” at the same time that the microcomputer enters the RAM back-up state, system reset may be performed. When using the watchdog timer and the RAM back-up mode, ini- tialize the WDF1 flag with the WRST instruction just before the microcomputer enters the RAM back-up state (refer to Figure 21) Fig. 21 Program example to enter the RAM back-up mode when using the watchdog timer WRST ; WDF1 flag reset

SINGLE-CHIP 4-BIT CMOS MICROCOMPUTER MITSUBISHI MICROCOMPUTERS SERIAL I/O The 4513/4514 Group has a built-in clock synchronous serial I/O which can serially transmit or receive 8-bit data. Serial I/O consists of;
- serial I/O register SI
- serial I/O mode register J1
- serial I/O transmission/reception completion flag (SIOF)
- serial I/O counter Registers A and B are used to perform data transfer with internal CPU, and the serial I/O pins are used for external data transfer. The pin functions of the serial I/O pins can be set with the register J1.

SINGLE-CHIP 4-BIT CMOS MICROCOMPUTER MITSUBISHI MICROCOMPUTERS Fig. 23 Serial I/O register state when transferring (1) Serial I/O register SI Serial I/O register SI is the 8-bit data transfer serial/parallel conver- sion register. Data can be set to register SI through registers A and B with the TSIAB instruction. The contents of register A is transmit- ted to the low-order 4 bits of register SI, and the contents of register B is transmitted to the high-order 4 bits of register SI. During transmission, each bit data is transmitted LSB first from the lowermost bit (bit 0) of register SI, and during reception, each bit data is received LSB first to register SI starting from the topmost bit (bit 7). When register SI is used as a work register without using serial I/O, pull up the S CK pin or set the pin function to an input port P20. (2) Serial I/O transmission/reception completion flag (SIOF) Serial I/O transmission/reception completion flag (SIOF) is set to “1” when serial data transmission or reception completes. The state of SIOF flag can be examined with the skip instruction (SNZSI). Use the interrupt control register V2 to select the inter- rupt or the skip instruction. The SIOF flag is cleared to “0” when the interrupt occurs or when the next instruction is skipped with the skip instruction.

Set the contents of this register through register A with the TJ1A instruction. The TAJ1 instruction can be used to transfer the contents of register J1 to register A.

However, do not execute this instruction during A- D conversion. When the contents of register AD is n, the logic value of the com- parison voltage V ref generated from the built-in DA converter can be obtained with the reference voltage VDD by the following for- mula: Logic value of comparison voltage Vref Vref = ✕ n n: The value of register AD (n = 0 to 1023) V DD 1024 (4) A-D conversion start instruction (ADST) A-D conversion starts when the ADST instruction is executed. The conversion result is automatically stored in the register AD. (5) A-D control register Q1 Register Q1 is used to select one of analog input pins. The 4513 Group does not have A IN4–A IN7. Accordingly, do not select these pins with register Q1. (6) A-D control register Q2 Register Q2 is used to select the pin function of P40/AIN4, P41/ A IN5, P42/AIN6, and P43/AIN7. The A-D conversion mode is se- lected when the bit 3 of register Q2 is “0,” and the comparator mode is selected when the bit 3 of register Q2 is “1.” After set this register, select the analog input with register Q1. Even when register Q2 is used to set the pins for analog input, 0/AIN4–P4 3/AIN7 continue to function as P40–P43 I/O. Accord- ingly, when any of them are used as I/O port P4 and others are used as analog input pins, make sure to set the outputs of pins that are set for analog input to “1.” Also, for the port input, the port input function of the pin functions as analog input is undefined. R/W R/W Table 15 A-D control registers (3) A-D conversion completion flag (ADF) A-D conversion completion flag (ADF) is set to “1” when A-D con- version completes. The state of ADF flag can be examined with the skip instruction (SNZAD). Use the interrupt control register V2 to select the interrupt or the skip instruction. The ADF flag is cleared to “0” when the interrupt occurs or when the next instruction is skipped with the skip instruction.

The internal operation during A-D conversion is as follows: ➀ When A-D conversion starts, the register AD is cleared to “00016.” ➁ Next, the topmost bit of the register AD is set to “1,” and the comparison voltage Vref is compared with the analog input volt- age VIN. ➂ When the comparison result is Vref < VIN, the topmost bit of the register AD remains set to “1.” When the comparison result is Vref > VIN, it is cleared to “0.” The 4513/4514 Group repeats this operation to the lowermost bit of the register AD to convert an analog value to a digital value. A-D conversion stops after 62 machine cycles (46.5 µs when f(XIN) =
4.0 MHz in high-speed mode) from the start, and the conversion re-
sult is stored in the register AD. An A-D interrupt activated condition is satisfied and the ADF flag is set to “1” as soon as A-D conversion completes (Figure 27). ✼ 1: 1st comparison result ✼ 3: 3rd comparison result ✼ 9: 9th comparison result ✼ 2: 2nd comparison result ✼ 8: 8th comparison result ✼ A: 10th comparison result 1st comparison 2nd comparison 3rd comparison After 10th comparison completes ✼ 1 ✼ 1 ✼ 1 ----- ----- ----- ----- ✼ 2 ✼ 2 ✼ 3 ✼ 8 ✼ 9 A-D conversion result V DD VDD VDD VDD VDD VDD VDD VDD 1024 ○○○○

Fig. 27 A-D conversion timing chart (9) How to use A-D conversion How to use A-D conversion is explained using as example in which the analog input from P40/AIN4 pin is A-D converted, and the high- order 4 bits of the converted data are stored in address M(Z, X, Y) = (0, 0, 0), the middle-order 4 bits in address M(Z, X, Y) = (0, 0, 1), and the low-order 2 bits in address M(Z, X, Y) = (0, 0, 2) of RAM. The A-D interrupt is not used in this example. ➀ After selecting the A IN4 pin function with the bit 0 of the register Q2, select AIN4 pin and A-D conversion mode with the register Q1 (refer to Figure 28). ➁ Execute the ADST instruction and start A-D conversion. ➂ Examine the state of ADF flag with the SNZAD instruction to de- termine the end of A-D conversion. ➃ Transfer the low-order 2 bits of converted data to the high-order 2 bits of register A (TALA instruction). ➄ Transfer the contents of register A to M (Z, X, Y) = (0, 0, 2). ➅ Transfer the high-order 8 bits of converted data to registers A and B (TABAD instruction). ➆ Transfer the contents of register A to M (Z, X, Y) = (0, 0, 1). ➇ Transfer the contents of register B to register A, and then, store into M(Z, X, Y) = (0, 0, 0).

SINGLE-CHIP 4-BIT CMOS MICROCOMPUTER MITSUBISHI MICROCOMPUTERS (10) Operation at comparator mode The A-D converter is set to comparator mode by setting bit 3 of the register Q2 to “1.” Below, the operation at comparator mode is described. (11) Comparator register In comparator mode, the built-in DA comparator is connected to the comparator register as a register for setting comparison voltages. The contents of register B is stored in the high-order 4 bits of the comparator register and the contents of register A is stored in the low-order 4 bits of the comparator register with the TADAB instruc- tion. When changing from A-D conversion mode to comparator mode, the result of A-D conversion (register AD) is undefined. However, because the comparator register is separated from regis- ter AD, the value is retained even when changing from comparator mode to A-D conversion mode. Note that the comparator register can be written and read at only comparator mode. If the value in the comparator register is n, the logic value of com- parison voltage V ref generated by the built-in DA converter can be determined from the following formula: (12) Comparison result store flag (ADF) In comparator mode, the ADF flag, which shows completion of A-D conversion, stores the results of comparing the analog input volt- age with the comparison voltage. When the analog input voltage is lower than the comparison voltage, the ADF flag is set to “1.” The state of ADF flag can be examined with the skip instruction (SNZAD). Use the interrupt control register V2 to select the inter- rupt or the skip instruction. The ADF flag is cleared to “0” when the interrupt occurs or when the next instruction is skipped with the skip instruction. (13) Comparator operation start instruction (ADST instruction) In comparator mode, executing ADST starts the comparator oper- ating. The comparator stops 8 machine cycles after it has started (6 µs at f(XIN) = 4.0 MHz in high-speed mode). When the analog input volt- age is lower than the comparison voltage, the ADF flag is set to “1.” (14) Notes for the use of A-D conversion 1 Note the following when using the analog input pins also for I/O port P4 functions:
- Even when P4 0/AIN4–P4 3/AIN7 are set to pins for analog input, they continue to function as P40–P4 3 I/O. Accordingly, when any of them are used as I/O port P4 and others are used as analog input pins, make sure to set the outputs of pins that are set for analog input to “1.” Also, the port input function of the pin func- tions as an analog input is undefined.
- TALA instruction When the TALA instruction is executed, the low-order 2 bits of register AD is transferred to the high-order 2 bits of register A, si- multaneously, the low-order 2 bits of register A is “0.” Logic value of comparison voltage Vref Vref = ✕ n n: The value of register AD (n = 0 to 255) Fig. 29 Comparator operation timing chart VDD 256 ADST instruction Comparison result store flag(ADF) 8 machine cycles DAC operation signal Comparator operation completed.

SINGLE-CHIP 4-BIT CMOS MICROCOMPUTER MITSUBISHI MICROCOMPUTERS (15) Notes for the use of A-D conversion 2 Do not change the operating mode (both A-D conversion mode and comparator mode) of A-D converter with bit 3 of register Q2 while A-D converter is operating. When the operating mode of A-D converter is changed from the comparator mode to A-D conversion mode with the bit 3 of register Q2, note the following;
- Clear bit 2 of register V2 to “0” to change the operating mode of the A-D converter from the comparator mode to A-D conversion mode with the bit 3 of register Q2.
- The A-D conversion completion flag (ADF) may be set when the operating mode of the A-D converter is changed from the com- parator mode to the A-D conversion mode. Accordingly, set a value to register Q2, and execute the SNZAD instruction to clear the ADF flag. (16) Definition of A-D converter accuracy The A-D conversion accuracy is defined below (refer to Figure 30).
- Relative accuracy ➀ Zero transition voltage (V0T) This means an analog input voltage when the actual A-D con- version output data changes from “0” to “1.” ➁ Full-scale transition voltage (VFST ) This means an analog input voltage when the actual A-D con- version output data changes from “1023” to ”1022.” ➂ Linearity error This means a deviation from the line between V0T and VFST of a converted value between V0T and VFST . ➃ Differential non-linearity error This means a deviation from the input potential difference re- quired to change a converter value between V 0T and VFST by 1 LSB at the relative accuracy.
- Absolute accuracy This means a deviation from the ideal characteristics between 0 to V DD of actual A-D conversion characteristics. Fig. 30 Definition of A-D conversion accuracy Vn: Analog input voltage when the output data changes from “n” to “n+1” (n = 0 to 1022)

SINGLE-CHIP 4-BIT CMOS MICROCOMPUTER MITSUBISHI MICROCOMPUTERS VOLTAGE COMPARATOR The 4513/4514 Group has 2 voltage comparator circuits that perform comparison of voltage between 2 pins. Table 17 shows the characteristics of this voltage comparison.

(1) Voltage comparator control register Q3 Register Q3 controls the function of the voltage comparator. The function of the voltage comparator CMP0 becomes valid by setting bit 2 of register Q3 to “1,” and becomes invalid by setting bit 2 of register Q3 to ”0.” The comparison result of the voltage com- parator CMP0 is stored into bit 0 of register Q3. The function of the voltage comparator CMP1 becomes valid by setting bit 3 of register Q3 to “1,” and becomes invalid by setting bit 3 of register Q3 to ”0.” The comparison result of the voltage com- parator CMP1 is stored into bit 1 of register Q3. (2) Operation description of voltage comparator The voltage comparator function becomes valid by setting each control bit of register Q3 to “1” and compares the voltage of the in- put pin. The comparison result is stored into each comparison result store bit of register Q3. The comparison result is as follows;
- When CMP0- > CMP0+, Q3 0 = “0” When CMP0- < CMP0+, Q3 0 = “1”
- When CMP1- > CMP1+, Q3 1 = “0” When CMP1- < CMP1+, Q3 1 = “1” (3) Precautions When the voltage comparator is used, note the following;
- Voltage comparator function When the voltage comparator function is valid with the voltage comparator control register Q3, it is operating even in the RAM back-up mode. Accordingly, be careful about such state because it causes the increase of the operation current in the RAM back- up mode. In order to reduce the operation current in the RAM back-up mode, invalidate (bits 2 and 3 of register Q3 = “0”) the voltage comparator function by software before the POF instruction is executed. Also, while the voltage comparator function is valid, current is al- ways consumed by voltage comparator. On the system required for the low-power dissipation, invalidate the voltage comparator by software when it is unused.
- Register Q3 Bits 0 and 1 of register Q3 can be only read. Note that they can- not be written.
- Reading the comparison result of voltage comparator Read the voltage comparator comparison result from register Q3 after the voltage comparator response time (max. 20 µ s) is passed from the voltage comparator function becomes valid. R/W Table 18 Voltage comparator control register Q3

SINGLE-CHIP 4-BIT CMOS MICROCOMPUTER MITSUBISHI MICROCOMPUTERS RAM BACK-UP MODE The 4513/4514 Group has the RAM back-up mode. When the EPOF and POF instructions are executed continuously, system enters the RAM back-up state. The POF instruction is equal to the NOP instruction when the EPOF instruction is not ex- ecuted before the POF instruction. As oscillation stops retaining RAM, the function of reset circuit and states at RAM back-up mode, current dissipation can be reduced without losing the contents of RAM. Table 20 shows the function and states retained at RAM back-up. Figure 38 shows the state transition. (1) Identification of the start condition Warm start (return from the RAM back-up state) or cold start (re- turn from the normal reset state) can be identified by examining the state of the power down flag (P) with the SNZP instruction. (2) Warm start condition When the external wakeup signal is input after the system enters the RAM back-up state by executing the EPOF and POF instruc- tions continuously, the CPU starts executing the program from address 0 in page 0. In this case, the P flag is “1.” (3) Cold start condition The CPU starts executing the program from address 0 in page 0 when;
- reset pulse is input to RESET pin, or
- reset by watchdog timer is performed, or
- voltage drop detection circuit detects the voltage drop. In this case, the P flag is “0.” Table 20 Functions and states retained at RAM back-up Function Program counter (PC), registers A, B, carry flag (CY), stack pointer (SP) (Note 2) Contents of RAM Port level Timer control register W1 Timer control registers W2 to W4, W6 Clock control register MR Interrupt control registers V1, V2 Interrupt control registers I1, I2 Timer 1 function Timer 2 function Timer 3 function Timer 4 function A-D conversion function A-D control registers Q1, Q2 Voltage comparator function Voltage comparator control register Q3 Serial I/O function Serial I/O mode register J1 Pull-up control register PU0 Key-on wakeup control register K0 Direction register FR0 External 0 interrupt request flag (EXF0) External 1 interrupt request flag (EXF1) Timer 1 interrupt request flag (T1F) Timer 2 interrupt request flag (T2F) Timer 3 interrupt request flag (T3F) Timer 4 interrupt request flag (T4F) Watchdog timer flags (WDF1, WDF2) Watchdog timer enable flag (WEF) 16-bit timer (WDT) A-D conversion completion flag (ADF) Serial I/O transmission/reception completion flag (SIOF) Interrupt enable flag (INTE) RAM back-up O O O O (Note 3) (Note 3) (Note 3) O O (Note 5) O O O O O (Note 3) (Note 3) (Note 3) ✕ (Note 4) ✕ (Note 4) ✕ (Note 4) Notes 1:“O” represents that the function can be retained, and “✕ ” repre- sents that the function is initialized.

SINGLE-CHIP 4-BIT CMOS MICROCOMPUTER MITSUBISHI MICROCOMPUTERS LIST OF PRECAUTIONS ➀ Noise and latch-up prevention Connect a capacitor on the following condition to prevent noise and latch-up;
- connect a bypass capacitor (approx. 0.1 µF) between pins VDD and VSS at the shortest distance,
- equalize its wiring in width and length, and
- use relatively thick wire. In the One Time PROM version, CNVSS pin is also used as VPP pin. Accordingly, when using this pin, connect this pin to VSS through a resistor about 5 kΩ in series at the shortest distance. ➁ Prescaler Stop the prescaler operation to change its frequency dividing ra- tio. ➂ Timer count source Stop timer 1, 2, 3, or 4 counting to change its count source. ➃ Reading the count value Stop timer 1, 2, 3, or 4 counting and then execute the TAB1, TAB2, TAB3, or TAB4 instruction to read its data. ➄ Writing to reload registers R1 and R3 When writing data to reload registers R1 or R3 while timer 1 or timer 3 is operating, avoid a timing when timer 1 or timer 3 underflows. ➅ P3 0/INT0 pin When the interrupt valid waveform of the P30/INT0 pin is changed with the bit 2 of register I1 in software, be careful about the following notes.
- Clear the bit 0 of register V1 to “0” before the interrupt valid wave- form of P3 0/INT0 pin is changed with the bit 2 of register I1 (refer to Figure 44➀ ).
- Depending on the input state of the P30/INT0 pin, the external 0 interrupt request flag (EXF0) may be set when the interrupt valid waveform is changed. Accordingly, clear bit 2 of register I1, and execute the SNZ0 instruction to clear the EXF0 flag after execut- ing at least one instruction (refer to Figure 44➁ ) Fig. 45 External 1 interrupt program example ➇ One Time PROM version The operating power voltage of the One Time PROM version is 2.5 V to 5.5 V. ➈ Multifunction The input of D 6, D7, P20–P22, I/O of P30 and P31, input of CMP0-, CMP0+, CMP1-, CMP1+, and I/O of P40–P43 can be used even when CNTR0, CNTR1, S CK , SOUT , SIN, INT0, INT1, AIN0–AIN3 and AIN4–AIN7 are selected. ➆ P31/INT1 pin When the interrupt valid waveform of P31/INT1 pin is changed with the bit 2 of register I2 in software, be careful about the fol- lowing notes.
- Clear the bit 1 of register V1 to “0” before the interrupt valid wave- form of P31/INT1 pin is changed with the bit 2 of register I2 (refer to Figure 45➂ ).
- Depending on the input state of the P31/INT1 pin, the external 1 interrupt request flag (EXF1) may be set when the interrupt valid waveform is changed. Accordingly, clear bit 2 of register I2 and execute the SNZ1 instruction to clear the EXF1 flag after execut- ing at least one instruction (refer to Figure 45➃ ).

- Clear the bit 2 of register V2 to “0” to change the operating mode of the A-D converter from the comparator mode to the A-D con- version mode with the bit 3 of register Q2 (refer to Figure 46➄ ).
- The A-D conversion completion flag (ADF) may be set when the operating mode of the A-D converter is changed from the com- parator mode to the A-D conversion mode. Accordingly, set a value to register Q2, and execute the SNZAD instruction to clear the ADF flag. Do not change the operating mode (both A-D conversion mode and comparator mode) of A-D converter with the bit 3 of register Q2 during operating the A-D converter. ...

Fig. 47 Analog input external circuit example-1 Fig. 48 Analog input external circuit example-2 POF instruction Execute the POF instruction immediately after executing the EPOF instruction to enter the RAM back-up. Note that system cannot enter the RAM back-up state when ex- ecuting only the POF instruction. Be sure to disable interrupts by executing the DI instruction be- fore executing the EPOF instruction. Analog input pins Note the following when using the analog input pins also for I/O port P4 functions:
- Even when P4 0/AIN4–P4 3/AIN7 are set to pins for analog input, they continue to function as P40–P4 3 I/O. Accordingly, when any of them are used as I/O port P4 and others are used as analog input pins, make sure to set the outputs of pins that are set for analog input to “1.” Also, the port input function of the pin func- tions as an analog input is undefined.
- TALA instruction When the TALA instruction is executed, the low-order 2 bits of register AD is transferred to the high-order 2 bits of register A, si- multaneously, the low-order 2 bits of register A is “0.” Program counter Make sure that the PC H does not specify after the last page of the built-in ROM. Port P3 In the 4513 Group, when the IAP3 instruction is executed, note that the high-order 2 bits of register A is undefined. A-D converter-2 Each analog input pin is equipped with a capacitor which is used to compare the analog voltage. Accordingly, when the analog voltage is input from the circuit with high-impedance and, charge/ discharge noise is generated and the sufficient A-D accuracy may not be obtained. Therefore, reduce the impedance or, con- nect a capacitor (0.01 µF to 1 µF) to analog input pins (Figure 47). When the overvoltage applied to the A-D conversion circuit may occur, connect an external circuit in order to keep the voltage within the rated range as shown the Figure 48. In addition, test the application products sufficiently. ✕ : this bit is not related to the change of the operating mode of the A-D conversion.

16 Voltage comparator function
When the voltage comparator function is valid with the voltage comparator control register Q3, it is operating even in the RAM back-up mode. Accordingly, be careful about such state because it causes the increase of the operation current in the RAM back- up mode. In order to reduce the operation current in the RAM back-up mode, invalidate (bits 2 and 3 of register Q3 = “0”) the voltage comparator function by software before the POF instruction is ex- ecuted. Also, while the voltage comparator function is valid, current is al- ways consumed by voltage comparator. On the system required for the low-power dissipation, invalidate the voltage comparator when it is unused by software. Register Q3 Bits 0 and 1 of register Q3 can be only read. Note that they can- not be written. Reading the comparison result of voltage comparator Read the voltage comparator comparison result from register Q3 after the voltage comparator response time (max. 20 µ s) is passed from the voltage comparator function become valid.

SINGLE-CHIP 4-BIT CMOS MICROCOMPUTER MITSUBISHI MICROCOMPUTERS Fig. 52 Flow of writing and test of the product shipped in blank Fig. 51 PROM memory map (1) PROM mode The built-in PROM version has a PROM mode in addition to a nor- mal operation mode. The PROM mode is used to write to and read from the built-in PROM. In the PROM mode, the programming adapter can be used with a general-purpose PROM programmer to write to or read from the built-in PROM as if it were M5M27C256K. Programming adapters are listed in Table 26.Contact addresses at the end of this sheet for the appropriate PROM programmer.
- Writing and reading of built-in PROM Programming voltage is 12.5 V. Write the program in the PROM of the built-in PROM version as shown in Figure 51. (2) Notes on handling ➀ A high-voltage is used for writing. Take care that overvoltage is not applied. Take care especially at turning on the power. ➁ For the One Time PROM version shipped in blank, Mitsubishi Electric corp. does not perform PROM writing test and screening in the assembly process and following processes. In order to im- prove reliability after writing, performing writing and test according to the flow shown in Figure 52 before using is recom- mended (Products shipped in blank: PROM contents is not written in factory when shipped).
