4.1 Introduction

4 Functional Description

The general architecture of the 3D-optical input device is shown in the system block diagram. The CPU is connected to the memory (FLASH and SRAM) and the peripheral modules via the internal system bus. The system bus provides a 16 bit address space and allows 8 and 16 bit data transfers. The memory contains the program code and the data. Memory and registers are mapped to the global memory map and can be accessed through all memory related operation provided by the CPUs instruction set. The memory of the IC consists a FLASH cell up to 30Kx22 (60KByte) including 6 additional bits per word used as CRC for error detection and error correction and a SRAM cell up to 1.5Kx18 (3KByte) including 2 bit parity per word. The Interrupt Controller collects requests from all interrupt sources and provides an interrupt signal to the CPU. Interrupt sources can be masked within the interrupt controller. Interrupts are generated by the modules and hold until they are cleared within the module. See module description for clearing procedures. The SPI can be configured either as a master or a slave. Transfer length is eight bit and can be extended by a mul- tiple of eight bit. Data FIFOs are provided for transmit and receive tasks. The SCI provides the standard NRZ (Non Return to Zero) mark/space data format where each frame contains one start bit, eight data bits and one stop bit. Several features are implemented for special LIN support. The timer module contains a 32 bit timer module as well as a watchdog timer. Additionally a second timer module operating on wake up clock is implemented that remains active even in off mode, so it can be used for a periodical wake up from off mode for applications that require a low current consumption. 8 IO port pins can either be configured as general purpose IO\`s or can be configured as ports for the SPI or SCI mod- ule. Additionally two ports are reserved for the I²C slave interface. The clock and reset generator module provides the system clock and the global reset signal. A power-on-reset, brown out detect and a power watch are implemented. As external reset source a reset input will be considered. The system clock is generated by an on-chip oscillators. A more detailed diagram of the clock/reset generation block (CRG) is shown in the following sections.

4.2 Supply Voltages

4.2.1 Block Diagram

4.2.2 Functional Description

4.2.3 Power Up Sequence Considerations

Figure 2: Block Diagram Supply Voltages The devices has three separated power domains and needs two different levels of power supplies. The core power domain is supplied by VDDC and the analog power domain by AVDD. Both needs the same voltage level. The third supply domain is supplied by VDDIO and powers GPIOs. See also 2.2 Recommended Operating Conditions. During power-up the power-on-reset configures all pads as inputs consequently disabling the output drivers. The IO supply is watched after power up if the core supply is in the specified range and causes a reset if it leaves the allowed region. The core supply is watched via a brown out circuit. The pads will remain input pads as long as the software does not reconfigure them. According the following diagram it must be guaranteed that ADVV / DVVC is not switched on before VDDIO. NRST can be switched on if the VDDIO and AVDD/DVVC are stabilized on its potential. A >= 0ms B > 5ms (recommended) To avoid floating gates, A < 100µs is recommended.

HALIOS® MULTI PURPOSE SENSOR FOR AUTOMOTIVE Figure 5: Timing of the external reset signal t Filtered by Debouncer NRST_PADin NRST_DEB TDEB_NRST The IC is equipped with a reset input pin which can be used to reset the chip. Any low pulse longer than TDEBNRST on the external reset line will be sensed and causes an IC reset. The IC contains different dynamic and static reset sources. The static sources trigger the master reset as long as the cause for the reset persists. The dynamic sources trigger the reset for a defined minimum reset time. After that time has expired the system reset is released. In case the dynamic source is still signaling a reset the reset is re-triggered. Static reset sources: - A power up sequence of the core voltage (power on reset) - Brown out of the core voltage Dynamic reset sources: - Uncorrectable FLASH CRC error - SRAM parity error - CPU register parity error - Watchdog timeout - Uncorrectable trim register ECC error

4.4 Reset Generation

4.4.1 Reset Generation (RESGEN)

4.3.2 Functional Description

The brown out detection of the chip will cause a reset whenever the core or IO power supply falls below the speci- fied region. An over-voltage protection is not implemented. The circuit will not be operational when the core sup- ply is below VDDmin. In these cases the power-on-reset will take care of proper reset generation.

4.5 System Failsafe Features

The power on reset is designed to cause a reset during the power on cycle of the chip. The reset will be deactivated when the supply crosses VPOR. After the power up sequence the power on reset block will only cause a new reset if the power supply voltage drops below VDDmin and the rise and fall times of the supply are below the specified values. failsafe feature asserts interrupt asserts reset FLASH CRC (bit error corrected) X FLASH CRC (uncorrectable bit error) X Empty (erased) FLASH word read detection X FLASH write detection X RAM byte parity X Uninitialized RAM word / byte read detection X CPU register parity X CPU undefined opcode detection X CPU misaligned word access detection X Opcode execution memory protection X Stack overflow detection X Invalid module register access detection X Watchdog time-out X Watchdog window protection X Brownout detection (supply voltage monitoring) X System clock monitoring X VDDC/AVDD VDDmin Brown Out Is not detectedEnd of Power-On-Reset t Vpor

4.6.2 HALIOS® Features

In order to be able to realize optical as well as capacitive sensors the input amplifier can be changed in its charac- teristic between transimpedance amplifier and charge amplifier. This is achieved by changing the feedback imped- ance. To have a good immunity to noise the receiving path consists of a symmetrical differential input. The HALIOS® IC contains a configurable current driver interface. In the case of an optical sensor it is possible to drive up to four sending LEDs and one compensation LED. If a capacitive sensor should be realized, the current is converted into a voltage by connecting pullup resistances at the outputs LEDx. The HALIOS® measurement loop is closed by a 10 bit DAC which regulates the output current for the sending/compensation LED. The DAC is control- led by a counter that sets the DAC dependent on the received signal amplitudes up or down. To follow fast signal changes the counter can be increased or decreased by 1, 2, 4 or 8 steps, this is called the step size that is set due to the number of up/down-counts in the same direction. To start a new measurement the in- terface is configured with the counter-value and the step size (generally the values from the last measurement), the LED configuration and the current configuration for the LED driver. The measurement regulates the DAC and performs 25 counter steps to follow the actual reflection conditions of the sensor. After one measurement the in- terface returns the counter-value, the mean-value (it is calculated from the last 16 counter-steps during one meas- urement) and the stepsize from the last integrator cycle.

5.3.1 Program Counter (PC)

5.3.2 Stack Pointer (SP)

5.3.3 Status Register (SR)

V: Overflow bit This bit is set when the result of an arithmetic operation overflows the signed-variable range. CLKOFF: Stop flag CPU clock gated CPUOFF: Standby flag CPU halted The 16-bit Program Counter (PC/R0) points to the next instruction to be executed. Each instruction uses an even number of bytes (two, four, or six), and the PC is incremented accordingly. Instruction accesses in the 64-KB address space are performed on word boundaries, and the PC is aligned to even addresses. The PC can be addressed with all instructions and addressing modes. The Stack Pointer (SP/R1) is used by the CPU to store the return addresses of subroutine calls and interrupts. It uses a pre-decrement, post-increment scheme. In addition, the SP can be used by software with all instructions and ad- dressing modes. The SP is initialized into RAM by the user, and is aligned to even addresses. The Status Register (SR/R2), used as a source or destination register, can be used in the register mode only ad - dressed with word instructions. The remaining combinations of addressing modes are used to support the con - stant generator.

5.3.4 Constant Generation Registers CG1 and CG2

5.3.5 General-Purpose Register R4 - R15

Six commonly-used constants are generated with the constant generator registers R2 and R3, without requiring an additional 16-bit word of program code. The constants are selected with the source-register addressing modes (As), as described in the table below: The twelve registers, R4-R15, are general-purpose registers. All of these registers can be used as data registers or address pointers and can be used with byte or word instructions. The constant generator advantages are: No special instructions required No additional code word for the six constants No code memory access required to retrieve the constant The assembler uses the constant generator automatically if one of the six constants is used as an immediate source operand. Registers R2 and R3, used in the constant mode, cannot be addressed explicitly; they act as source- only registers. Register Name As Value Remarks R2 00 - register mode (access R2) R2 01 (0) used for absolute address mode R2 10 0x0004 constant +4 R2 11 0x0008 constant +8 R3 00 0x0000 constant 0 R3 01 0x0001 constant +1 R3 10 0x0002 constant +2 R3 11 0xFFFF constant -1 GIE: Global Interrupt Enable N: Negative bit This bit is set when the result of a byte or word operation is negative and cleared when the result is not negative. Word operation: N is set to the value of bit 15 of the result Byte operation: N is set to the value of bit 7 of the result Z: Zero bit This bit is set when the result of a byte or word operation is 0 and cleared when the result is not 0. C: Carry bit This bit is set when the result of a byte or word operation produced a carry and cleared when no carry occurred.

5.4 Addressing Modes

5.5 EL16 Instruction Set

Seven addressing modes for the source operand and four addressing modes for the destination operand can ad- dress the complete address space with no exceptions. The bit numbers in the table below describe the contents of the As (source) and Ad (destination) mode bits. The complete EL16 instruction set consists of 27 instructions. There are three instruction formats: ÿ Dual-operand ÿ Single-operand ÿ Jump All dual-operand and single-operand instructions can be byte or word instructions by using .B or .W extensions. Byte instructions are used to access byte data. Word instructions are used to access word data. If no explicit exten- sion is used, the instruction is a word instruction. The source and destination of an instruction are defined by the following fields: Abbr. Description src The source operand defined by As and S-reg dst The destination operand defined by Ad and D-reg As The addressing bits responsible for the addressing mode used for the source (src) S-reg The working register used for the source (src) Ad The addressing bits responsible for the addressing mode used for the destination (dst) D-reg The working register used for the destination (dst) B/W Byte or word operation: 0: word operation, 1: byte operation As/Ad Addressing Mode Syntax Description 00/0 Register mode Rn Register contents are operand 01/1 Indexed mode X(Rn) (Rn + X) point to the operand. X is stored in the next word. 01/1 Symbolic mode ADDR (Rn + X) point to the operand. X is stored in the next word. Indexed mode X(PC) is used. 01/1 Absolute mode &ADDR (Rn + X) point to the operand. X is stored in the next word. Indexed mode X(0) is used. 10/- Indirect Register mode @Rn Rn is used as a pointer to the 11/- Indirect auto increment @Rn+ Rn is used as a pointer to the operand. Rn is incremented afterwards by 1 for .B instructions and by 2 for .W instructions 11/- Immediate mode #N The word following the instruction contains the immediate constant N. Indirect auto-increment mode @PC+ is used.

5.11.5 Data FIFO Registers

Receive Data FIFO Registers: The data received from the master is stored in the receive FIFO registers and has a depth of 4. The current fill level can be read in the status register. If the FIFO is completely filled up and another byte should be received the interface will force the master into a wait state until the application software reads one byte from the FIFO. Send Data FIFO Registers: The master reads data that is stored in the send FIFO registers. This FIFO buffer has a depth of 4 registers. The current fill level can be read in the status register. If the FIFO is empty and a byte is requested by the master the interface will force the master into a wait state until the application software writes one byte to the FIFO.

5.11.6 Interrupt Handling

I²C receive command (see List Of All Interrupts) Command word pending in receive FIFO, this means the next byte read from the receive FIFO is the first received byte after the slave has been addressed. Depending on the application software this byte could be interpreted as a command. The interrupt flag is set back by reading a byte from the receive FIFO. The master will force the inter- face into a wait state until the application software reads one byte from the FIFO. I²C send request (see List Of All Interrupts) This flag signalizes that the master is requesting a byte but the send FIFO is empty. The interrupt flag is set back by writing a byte to the send FIFO. The master will force the interface into a wait state until the application soft- ware writes one byte to the FIFO. I²C send FIFO low water (see List Of All Interrupts) In case the low water mark (defined in control register) is reached or is exceeded the send FIFO low water flag be- comes active. The flag is set back by filling to the send FIFO. I²C receive FIFO high water (see List Of All Interrupts) If the high water mark (defined in control register) is reached or is exceeded the receive FIFO high water flag be- comes active. The flag is set back by reading from the receive FIFO..

5.12.1 Interrupt Control Module Structure

5.11.7 I²C Wake-up Detection

The I²C interface can be used to wake up the IC from any system state. In system state "off" the interface has to be configured to wake the CPU Therefore the 'wake-up mode enable bit' has to be set (defined in control register) before setting the IC to "off-mode". It is only possible to set the 'wake-up mode enable bit' if the I²C Master has closed the communication on the bus, so the application software has to poll the bit 'wake-up mode enable' (defined in status register) after it was set to make sure the bus is in idle state and the IC can be set to "off-mode". After a new addressing of the slave on the bus the system will wake up from "off-mode" and the "I²C wake-up event" interrupt is active as long as the 'wake-up mode enable bit' is set back to zero (defined in control register). While the wake-up process the interface will force the Master into a wait state by holding the SCL line low. The application software has to clear the 'wake-up mode enable bit' (defined in control register) to release the SCL line in order to continue the communication.

BDFA[00000] = 0/32 = 0 BDFA[00001] = 1/32 = 0.03125 BDFA[00010] = 2/32 = 0.0625 ... BDFA[10000] = 16/32 = 0.5 ...

The baud divi- sor fine adjust can be used to fine tune the baud rate in 1/32 steps of the divisor. Use the following formula to calculate the SCI baud rate: Baud Rate = clksys/(16*(BD+BDFA)) Note: The 16 bit baud divisor value represents the number of system clock cycles of two bit lengths. The result of a baud measurement(see measurement counter below) can directly be written to the baud rate register.
