General Device Information Table 2 Pin Definitions and Functions Input Outp. I Function Reset Input with Schmitt-Trigger characteristics. A low level at this pin while the oscillator is running resets the XC164D. A spike filter suppresses input pulses <10 ns. Input pulses >100 ns safely pass the filter. The minimum duration for a safe recognition should be 100 ns + 2 CPU clock cycles. Note: The reset duration must be sufficient to let the hardware configuration signals settle. External circuitry must guarantee low level at the RSTIN pin at least until both power supply voltages have reached the operating range. P20.12 2 NMI 3 IO I For details, please refer to the description of P20. Non-Maskable Interrupt Input. A high to low transition at this pin causes the CPU to vector to the NMI trap routine. When the PWRDN (power down) instruction is executed, the NMI pin must be low in order to force the XC164D into power down mode. If NMI is high, when PWRDN is executed, the part will continue to run in normal mode. If not used, pin NMI should be pulled high externally. For details, please refer to the description of PORT0.

General Device Information Table 2 Pin Definitions and Functions (cont'd) Input Outp. IO Function Port 20 is a 5-bit bidirectional I/O port. Each pin can be programmed for input (output driver in high-impedance state) or output. The input threshold of Port 20 is selectable (standard or special). The following Port 20 pins also serve for alternate functions: RD External Memory Read Strobe, activated for every external instruction or data read access. WR/WRL External Memory Write Strobe. In WR-mode this pin is activated for every external data write access. In WRL-mode this pin is activated for low byte data write accesses on a 16-bit bus, and for every data write access on an 8-bit bus. ALE Address Latch Enable Output. Can be used for latching the address into external memory or an address latch in the multiplexed bus modes. EA External Access Enable pin. A low level at this pin during and after Reset forces the XC164D to latch the configuration from PORT0 and pin RD, and to begin instruction execution out of external memory. A high level forces the XC164D to latch the configuration from pins RD, ALE, and WR, and to begin instruction execution out of the internal program memory. "ROMless" versions must have this pin tied to `0'. RSTOUT Internal Reset Indication Output. Is activated asynchronously with an external hardware reset. It may also be activated (selectable) synchronously with an internal software or watchdog reset. Is deactivated upon the execution of the EINIT instruction, optionally at the end of reset, or at any time (before EINIT) via user software. Note: Port 20 pins may input configuration values (see EA).

Functional Description
The architecture of the XC164D combines advantages of RISC, CISC, and DSP processors with an advanced peripheral subsystem in a very well-balanced way. In addition, the on-chip memory blocks allow the design of compact systems-on-silicon with maximum performance (computing, control, communication). The on-chip memory blocks (program code-memory and SRAM, dual-port RAM, data SRAM) and the set of generic peripherals are connected to the CPU via separate buses. Another bus, the LXBus, connects additional on-chip resoures as well as external resources (see Figure 3). This bus structure enhances the overall system performance by enabling the concurrent operation of several subsystems of the XC164D. The following block diagram gives an overview of the different on-chip components and of the advanced, high bandwidth internal bus structure of the XC164D.

Memory Subsystem and Organization
The memory space of the XC164D is configured in a Von Neumann architecture, which means that all internal and external resources, such as code memory, data memory, registers and I/O ports, are organized within the same linear address space. This common memory space includes 16 Mbytes and is arranged as 256 segments of 64 Kbytes each, where each segment consists of four data pages of 16 Kbytes each. The entire memory space can be accessed bytewise or wordwise. Portions of the onchip DPRAM and the register spaces (E/SFR) have additionally been made directly bitaddressable. The internal data memory areas and the Special Function Register areas (SFR and ESFR) are mapped into segment 0, the system segment. The Program Management Unit (PMU) handles all code fetches and, therefore, controls accesses to the program memories, such as Flash memory and PSRAM. The Data Management Unit (DMU) handles all data transfers and, therefore, controls accesses to the DSRAM and the on-chip peripherals. Both units (PMU and DMU) are connected via the high-speed system bus to exchange data. This is required if operands are read from program memory, code or data is written to the PSRAM, code is fetched from external memory, or data is read from or written to external resources, including peripherals on the LXbus (such as TwinCAN). The system bus allows concurrent two-way communication for maximum transfer performance. 128 Kbytes of on-chip Flash memory store code or constant data. The on-chip Flash memory is organized as four 8-Kbyte sectors, one 32-Kbyte sector, and three 64-Kbyte sectors. Each sector can be separately write protected1), erased and programmed (in blocks of 128 Bytes). The complete Flash area can be read-protected. A password sequence temporarily unlocks protected areas. The Flash module combines very fast 64-bit one-cycle read accesses with protected and efficient writing algorithms for programming and erasing. Thus, program execution out of the internal Flash results in maximum performance. Dynamic error correction provides extremely high read data security for all read accesses. Programming typically takes 2 ms per 128-byte block (5 ms max.), erasing a sector typically takes 200 ms (500 ms max.). 2 Kbytes of on-chip Program SRAM (PSRAM) are provided to store user code or data. The PSRAM is accessed via the PMU and is therefore optimized for code fetches. 2 Kbytes of on-chip Data SRAM (DSRAM) are provided as a storage for general user data.The DSRAM is accessed via the DMU and is therefore optimized for data accesses. 2 Kbytes of on-chip Dual-Port RAM (DPRAM) are provided as a storage for user defined variables, for the system stack, general purpose register banks. A register bank can consist of up to 16 wordwide (R0 to R15) and/or bytewide (RL0, RH0, ..., RL7, RH7)
1) Each two 8-Kbyte sectors are combined for write-protection purposes.

Functional Description so-called General Purpose Registers (GPRs). The upper 256 bytes of the DPRAM are directly bitaddressable. When used by a GPR, any location in the DPRAM is bitaddressable. 1024 bytes (2 x 512 bytes) of the address space are reserved for the Special Function Register areas (SFR space and ESFR space). SFRs are wordwide registers which are used for controlling and monitoring functions of the different on-chip units. Unused SFR addresses are reserved for future members of the XC166 Family. Therefore, they should either not be accessed, or written with zeros, to ensure upward compatibility. In order to meet the needs of designs where more memory is required than is provided on chip, up to 12 Mbytes (approximately, see Table 3) of external RAM and/or ROM can be connected to the microcontroller. The External Bus Interface also provides access to external peripherals. Table 3 XC164D Memory Map1) Start Loc.

External Bus Controller
All of the external memory accesses are performed by a particular on-chip External Bus Controller (EBC). It can be programmed either to Single Chip Mode when no external memory is required, or to one of four different external memory access modes1), which are as follows: - - - - 16 ... 24-bit Addresses, 16-bit Data, Demultiplexed 16 ... 24-bit Addresses, 16-bit Data, Multiplexed 16 ... 24-bit Addresses, 8-bit Data, Multiplexed 16 ... 24-bit Addresses, 8-bit Data, Demultiplexed
In the demultiplexed bus modes, addresses are output on PORT1 and data is input/output on PORT0 or P0L, respectively. In the multiplexed bus modes both addresses and data use PORT0 for input/output. The high order address (segment) lines use Port 4. The number of active segment address lines is selectable, restricting the external address space to 8 Mbytes ... 64 Kbytes. This is required when interface lines are assigned to Port 4. Up to 4 external CS signals (3 windows plus default) can be generated in order to save external glue logic. External modules can directly be connected to the common address/data bus and their individual select lines. Important timing characteristics of the external bus interface have been made programmable (via registers TCONCSx/FCONCSx) to allow the user the adaption of a wide range of different types of memories and external peripherals. In addition, up to 4 independent address windows may be defined (via registers ADDRSELx) which control the access to different resources with different bus characteristics. These address windows are arranged hierarchically where window 4 overrides window 3, and window 2 overrides window 1. All accesses to locations not covered by these 4 address windows are controlled by TCONCS0/FCONCS0. The currently active window can generate a chip select signal. The external bus timing is related to the rising edge of the reference clock output CLKOUT. The external bus protocol is compatible with that of the standard C166 Family. The EBC also controls accesses to resources connected to the on-chip LXBus. The LXBus is an internal representation of the external bus and allows accessing integrated peripherals and modules in the same way as external components. The TwinCAN module is connected and accessed via the LXBus.
1) Bus modes are switched dynamically if several address windows with different mode settings are used.

Based on these hardware provisions, most of the XC164D's instructions can be executed in just one machine cycle which requires 25 ns at 40 MHz CPU clock. For example, shift and rotate instructions are always processed during one machine cycle independent of the number of bits to be shifted. Also multiplication and most MAC instructions execute in one single cycle. All multiple-cycle instructions have been optimized so that they can be executed very fast as well: for example, a 32-/16-bit division is started within 4 cycles, while the remaining 15 cycles are executed in the

Functional Description background. Another pipeline optimization, the branch target prediction, allows eliminating the execution time of branch instructions if the prediction was correct. The CPU has a register context consisting of up to three register banks with 16 wordwide GPRs each at its disposal. One of these register banks is physically allocated within the on-chip DPRAM area. A Context Pointer (CP) register determines the base address of the active register bank to be accessed by the CPU at any time. The number of register banks is only restricted by the available internal RAM space. For easy parameter passing, a register bank may overlap others. A system stack of up to 32 Kwords is provided as a storage for temporary data. The system stack can be allocated to any location within the address space (preferably in the on-chip RAM area), and it is accessed by the CPU via the stack pointer (SP) register. Two separate SFRs, STKOV and STKUN, are implicitly compared against the stack pointer value upon each stack access for the detection of a stack overflow or underflow. The high performance offered by the hardware implementation of the CPU can efficiently be utilized by a programmer via the highly efficient XC164D instruction set which includes the following instruction classes: - - - - - - - - - - - - - Standard Arithmetic Instructions DSP-Oriented Arithmetic Instructions Logical Instructions Boolean Bit Manipulation Instructions Compare and Loop Control Instructions Shift and Rotate Instructions Prioritize Instruction Data Movement Instructions System Stack Instructions Jump and Call Instructions Return Instructions System Control Instructions Miscellaneous Instructions
The basic instruction length is either 2 or 4 bytes. Possible operand types are bits, bytes and words. A variety of direct, indirect or immediate addressing modes are provided to specify the required operands.

Interrupt System
With an interrupt response time of typically 8 CPU clocks (in case of internal program execution), the XC164D is capable of reacting very fast to the occurrence of nondeterministic events. The architecture of the XC164D supports several mechanisms for fast and flexible response to service requests that can be generated from various sources internal or external to the microcontroller. Any of these interrupt requests can be programmed to being serviced by the Interrupt Controller or by the Peripheral Event Controller (PEC). In contrast to a standard interrupt service where the current program execution is suspended and a branch to the interrupt vector table is performed, just one cycle is `stolen' from the current CPU activity to perform a PEC service. A PEC service implies a single byte or word data transfer between any two memory locations with an additional increment of either the PEC source, or the destination pointer, or both. An individual PEC transfer counter is implicitly decremented for each PEC service except when performing in the continuous transfer mode. When this counter reaches zero, a standard interrupt is performed to the corresponding source related vector location. PEC services are very well suited, for example, for supporting the transmission or reception of blocks of data. The XC164D has 8 PEC channels each of which offers such fast interrupt-driven data transfer capabilities. A separate control register which contains an interrupt request flag, an interrupt enable flag and an interrupt priority bitfield exists for each of the possible interrupt nodes. Via its related register, each node can be programmed to one of sixteen interrupt priority levels. Once having been accepted by the CPU, an interrupt service can only be interrupted by a higher prioritized service request. For the standard interrupt processing, each of the possible interrupt nodes has a dedicated vector location. Fast external interrupt inputs are provided to service external interrupts with high precision requirements. These fast interrupt inputs feature programmable edge detection (rising edge, falling edge, or both edges). Software interrupts are supported by means of the `TRAP' instruction in combination with an individual trap (interrupt) number. Table 4 shows all of the possible XC164D interrupt sources and the corresponding hardware-related interrupt flags, vectors, vector locations and trap (interrupt) numbers. Note: Interrupt nodes which are not assigned to peripherals (unassigned nodes), may be used to generate software controlled interrupt requests by setting the respective interrupt request bit (xIR).

XC164D Derivatives
Functional Description The XC164D also provides an excellent mechanism to identify and to process exceptions or error conditions that arise during run-time, so-called `Hardware Traps'. Hardware traps cause immediate non-maskable system reaction which is similar to a standard interrupt service (branching to a dedicated vector table location). The occurence of a hardware trap is additionally signified by an individual bit in the trap flag register (TFR).

On-Chip Debug Support (OCDS)
The On-Chip Debug Support system provides a broad range of debug and emulation features built into the XC164D. The user software running on the XC164D can thus be debugged within the target system environment. The OCDS is controlled by an external debugging device via the debug interface, consisting of the IEEE-1149-conforming JTAG port and a break interface. The debugger controls the OCDS via a set of dedicated registers accessible via the JTAG interface. Additionally, the OCDS system can be controlled by the CPU, e.g. by a monitor program. An injection interface allows the execution of OCDS-generated instructions by the CPU. Multiple breakpoints can be triggered by on-chip hardware, by software, or by an external trigger input. Single stepping is supported as well as the injection of arbitrary instructions and read/write access to the complete internal address space. A breakpoint trigger can be answered with a CPU-halt, a monitor call, a data transfer, or/and the activation of an external signal. Tracing data can be obtained via the JTAG interface or via the external bus interface for increased performance. The debug interface uses a set of 6 interface signals (4 JTAG lines, 2 break lines) to communicate with external circuitry. These interface signals are realized as alternate functions on Port 3 pins. Complete system emulation is supported by the New Emulation Technology (NET) interface. Via this full-featured emulation interface (including internal buses, control, status, and pad signals) the XC164D chip can be connected to a NET carrier chip. The use of the XC164D production chip together with the carrier chip provides superior emulation behavior, because the emulation system shows exactly the same functionality as the production chip (use of the identical silicon).

Capture/Compare Units (CAPCOM1/2)
The CAPCOM units support generation and control of timing sequences on up to 32 channels with a maximum resolution of 1 system clock cycle (8 cycles in staggered mode). The CAPCOM units are typically used to handle high speed I/O tasks such as pulse and waveform generation, pulse width modulation (PMW), Digital to Analog (D/A) conversion, software timing, or time recording relative to external events. Four 16-bit timers (T0/T1, T7/T8) with reload registers provide two independent time bases for each capture/compare register array. The input clock for the timers is programmable to several prescaled values of the internal system clock, or may be derived from an overflow/underflow of timer T6 in module GPT2. This provides a wide range of variation for the timer period and resolution and allows precise adjustments to the application specific requirements. In addition, external count inputs for CAPCOM timers T0 and T7 allow event scheduling for the capture/compare registers relative to external events. Both of the two capture/compare register arrays contain 16 dual purpose capture/compare registers, each of which may be individually allocated to either CAPCOM timer T0 or T1 (T7 or T8, respectively), and programmed for capture or compare function. 12 registers of the CAPCOM2 module have each one port pin associated with it which serves as an input pin for triggering the capture function, or as an output pin to indicate the occurrence of a compare event. Table 6 Mode 0 Mode 1 Mode 2 Mode 3 Double Register Mode Single Event Mode Compare Modes (CAPCOM1/2) Function Interrupt-only compare mode; several compare interrupts per timer period are possible Pin toggles on each compare match; several compare events per timer period are possible Interrupt-only compare mode; only one compare interrupt per timer period is generated Pin set `1' on match; pin reset `0' on compare timer overflow; only one compare event per timer period is generated Two registers operate on one pin; pin toggles on each compare match; several compare events per timer period are possible Generates single edges or pulses; can be used with any compare mode

Functional Description When a capture/compare register has been selected for capture mode, the current contents of the allocated timer will be latched (`captured') into the capture/compare register in response to an external event at the port pin which is associated with this register. In addition, a specific interrupt request for this capture/compare register is generated. Either a positive, a negative, or both a positive and a negative external signal transition at the pin can be selected as the triggering event. The contents of all registers which have been selected for one of the five compare modes are continuously compared with the contents of the allocated timers. When a match occurs between the timer value and the value in a capture/compare register, specific actions will be taken based on the selected compare mode.

The Capture/Compare Unit CAPCOM6
The CAPCOM6 unit supports generation and control of timing sequences on up to three 16-bit capture/compare channels plus one independent 10-bit compare channel. In compare mode the CAPCOM6 unit provides two output signals per channel which have inverted polarity and non-overlapping pulse transitions (deadtime control). The compare channel can generate a single PWM output signal and is further used to modulate the capture/compare output signals. In capture mode the contents of compare timer T12 is stored in the capture registers upon a signal transition at pins CCx. Compare timers T12 (16-bit) and T13 (10-bit) are free running timers which are clocked by the prescaled system clock.

General Purpose Timer (GPT12E) Unit
The GPT12E unit represents a very flexible multifunctional timer/counter structure which may be used for many different time related tasks such as event timing and counting, pulse width and duty cycle measurements, pulse generation, or pulse multiplication. The GPT12E unit incorporates five 16-bit timers which are organized in two separate modules, GPT1 and GPT2. Each timer in each module may operate independently in a number of different modes, or may be concatenated with another timer of the same module. Each of the three timers T2, T3, T4 of module GPT1 can be configured individually for one of four basic modes of operation, which are Timer, Gated Timer, Counter, and Incremental Interface Mode. In Timer Mode, the input clock for a timer is derived from the system clock, divided by a programmable prescaler, while Counter Mode allows a timer to be clocked in reference to external events. Pulse width or duty cycle measurement is supported in Gated Timer Mode, where the operation of a timer is controlled by the `gate' level on an external input pin. For these purposes, each timer has one associated port pin (TxIN) which serves as gate or clock input. The maximum resolution of the timers in module GPT1 is 4 system clock cycles. The count direction (up/down) for each timer is programmable by software or may additionally be altered dynamically by an external signal on a port pin (TxEUD) to facilitate e.g. position tracking. In Incremental Interface Mode the GPT1 timers (T2, T3, T4) can be directly connected to the incremental position sensor signals A and B via their respective inputs TxIN and TxEUD. Direction and count signals are internally derived from these two input signals, so the contents of the respective timer Tx corresponds to the sensor position. The third position sensor signal TOP0 can be connected to an interrupt input. Timer T3 has an output toggle latch (T3OTL) which changes its state on each timer overflow/underflow. The state of this latch may be output on pin T3OUT e.g. for time out monitoring of external hardware components. It may also be used internally to clock timers T2 and T4 for measuring long time periods with high resolution. In addition to their basic operating modes, timers T2 and T4 may be configured as reload or capture registers for timer T3. When used as capture or reload registers, timers T2 and T4 are stopped. The contents of timer T3 is captured into T2 or T4 in response to a signal at their associated input pins (TxIN). Timer T3 is reloaded with the contents of T2 or T4 triggered either by an external signal or by a selectable state transition of its toggle latch T3OTL. When both T2 and T4 are configured to alternately reload T3 on opposite state transitions of T3OTL with the low and high times of a PWM signal, this signal can be constantly generated without software intervention.

With its maximum resolution of 2 system clock cycles, the GPT2 module provides precise event control and time measurement. It includes two timers (T5, T6) and a capture/reload register (CAPREL). Both timers can be clocked with an input clock which is derived from the CPU clock via a programmable prescaler or with external signals. The count direction (up/down) for each timer is programmable by software or may additionally be altered dynamically by an external signal on a port pin (TxEUD). Concatenation of the timers is supported via the output toggle latch (T6OTL) of timer T6, which changes its state on each timer overflow/underflow. The state of this latch may be used to clock timer T5, and/or it may be output on pin T6OUT. The overflows/underflows of timer T6 can additionally be used to clock the CAPCOM1/2 timers, and to cause a reload from the CAPREL register. The CAPREL register may capture the contents of timer T5 based on an external signal transition on the corresponding port pin (CAPIN), and timer T5 may optionally be cleared

Real Time Clock
The Real Time Clock (RTC) module of the XC164D is directly clocked via a separate clock driver with the prescaled on-chip oscillator frequency (fRTC = fOSC / 32). It is therefore independent from the selected clock generation mode of the XC164D. The RTC basically consists of a chain of divider blocks: * * * a selectable 8:1 divider (on - off) the reloadable 16-bit timer T14 the 32-bit RTC timer block (accessible via registers RTCH and RTCL), made of: - a reloadable 10-bit timer - a reloadable 6-bit timer - a reloadable 6-bit timer - a reloadable 10-bit timer
All timers count up. Each timer can generate an interrupt request. All requests are combined to a common node request.

Asynchronous/Synchronous Serial Interfaces (ASC0/ASC1)
The Asynchronous/Synchronous Serial Interfaces ASC0/ASC1 (USARTs) provide serial communication with other microcontrollers, processors, terminals or external peripheral components. They are upward compatible with the serial ports of the Infineon 8-bit microcontroller families and support full-duplex asynchronous communication and halfduplex synchronous communication. A dedicated baud rate generator with a fractional divider precisely generates all standard baud rates without oscillator tuning. For transmission, reception, error handling, and baudrate detection 5 separate interrupt vectors are provided. In asynchronous mode, 8- or 9-bit data frames (with optional parity bit) are transmitted or received, preceded by a start bit and terminated by one or two stop bits. For multiprocessor communication, a mechanism to distinguish address from data bytes has been included (8-bit data plus wake-up bit mode). IrDA data transmissions up to 115.2 kbit/s with fixed or programmable IrDA pulse width are supported. In synchronous mode, bytes (8 bits) are transmitted or received synchronously to a shift clock which is generated by the ASC0/1. The LSB is always shifted first. In both modes, transmission and reception of data is FIFO-buffered. An autobaud detection unit allows to detect asynchronous data frames with its baudrate and mode with automatic initialization of the baudrate generator and the mode control bits. A number of optional hardware error detection capabilities has been included to increase the reliability of data transfers. A parity bit can automatically be generated on transmission or be checked on reception. Framing error detection allows to recognize data frames with missing stop bits. An overrun error will be generated, if the last character received has not been read out of the receive buffer register at the time the reception of a new character is complete. Summary of Features * Full-duplex asynchronous operating modes - 8- or 9-bit data frames, LSB first, one or two stop bits, parity generation/checking - Baudrate from 2.5 Mbit/s to 0.6 bit/s (@ 40 MHz) - Multiprocessor mode for automatic address/data byte detection - Support for IrDA data transmission/reception up to max. 115.2 kbit/s (@ 40 MHz) - Loop-back capability - Auto baudrate detection Half-duplex 8-bit synchronous operating mode at 5 Mbit/s to 406.9 bit/s (@ 40 MHz) Buffered transmitter/receiver with FIFO support (8 entries per direction) Loop-back option available for testing purposes Interrupt generation on transmitter buffer empty condition, last bit transmitted condition, receive buffer full condition, error condition (frame, parity, overrun error), start and end of an autobaud detection

High Speed Synchronous Serial Channels (SSC0/SSC1)
The High Speed Synchronous Serial Channels SSC0/SSC1 support full-duplex and halfduplex synchronous communication. It may be configured so it interfaces with serially linked peripheral components, full SPI functionality is supported. A dedicated baud rate generator allows to set up all standard baud rates without oscillator tuning. For transmission, reception and error handling three separate interrupt vectors are provided. The SSC transmits or receives characters of 2 ... 16 bits length synchronously to a shift clock which can be generated by the SSC (master mode) or by an external master (slave mode). The SSC can start shifting with the LSB or with the MSB and allows the selection of shifting and latching clock edges as well as the clock polarity. A number of optional hardware error detection capabilities has been included to increase the reliability of data transfers. Transmit error and receive error supervise the correct handling of the data buffer. Phase error and baudrate error detect incorrect serial data. Summary of Features * * * * Master or Slave mode operation Full-duplex or Half-duplex transfers Baudrate generation from 20 Mbit/s to 305.18 bit/s (@ 40 MHz) Flexible data format - Programmable number of data bits: 2 to 16 bits - Programmable shift direction: LSB-first or MSB-first - Programmable clock polarity: idle low or idle high - Programmable clock/data phase: data shift with leading or trailing clock edge Loop back option available for testing purposes Interrupt generation on transmitter buffer empty condition, receive buffer full condition, error condition (receive, phase, baudrate, transmit error) Three pin interface with flexible SSC pin configuration

TwinCAN Module
The integrated TwinCAN module handles the completely autonomous transmission and reception of CAN frames in accordance with the CAN specification V2.0 part B (active), i.e. the on-chip TwinCAN module can receive and transmit standard frames with 11-bit identifiers as well as extended frames with 29-bit identifiers. Two Full-CAN nodes share the TwinCAN module's resources to optimize the CAN bus traffic handling and to minimize the CPU load. The module provides up to 32 message objects, which can be assigned to one of the CAN nodes and can be combined to FIFOstructures. Each object provides separate masks for acceptance filtering. The flexible combination of Full-CAN functionality and FIFO architecture reduces the efforts to fulfill the real-time requirements of complex embedded control applications. Improved CAN bus monitoring functionality as well as the number of message objects permit precise and comfortable CAN bus traffic handling. Gateway functionality allows automatic data exchange between two separate CAN bus systems, which reduces CPU load and improves the real time behavior of the entire system. The bit timing for both CAN nodes is derived from the master clock and is programmable up to a data rate of 1 Mbit/s. Each CAN node uses two pins of Port 4 or Port 9 to interface to an external bus transceiver. The interface pins are assigned via software.

Watchdog Timer
The Watchdog Timer represents one of the fail-safe mechanisms which have been implemented to prevent the controller from malfunctioning for longer periods of time. The Watchdog Timer is always enabled after a reset of the chip, and can be disabled until the EINIT instruction has been executed (compatible mode), or it can be disabled and enabled at any time by executing instructions DISWDT and ENWDT (enhanced mode). Thus, the chip's start-up procedure is always monitored. The software has to be designed to restart the Watchdog Timer before it overflows. If, due to hardware or software related failures, the software fails to do so, the Watchdog Timer overflows and generates an internal hardware reset and pulls the RSTOUT pin low in order to allow external hardware components to be reset. The Watchdog Timer is a 16-bit timer, clocked with the system clock divided by 2/4/128/256. The high byte of the Watchdog Timer register can be set to a prespecified reload value (stored in WDTREL) in order to allow further variation of the monitored time interval. Each time it is serviced by the application software, the high byte of the Watchdog Timer is reloaded and the low byte is cleared. Thus, time intervals between 13 s and 419 ms can be monitored (@ 40 MHz). The default Watchdog Timer interval after reset is 3.28 ms (@ 40 MHz).

Clock Generation
The Clock Generation Unit uses a programmable on-chip PLL with multiple prescalers to generate the clock signals for the XC164D with high flexibility. The master clock fMC is the reference clock signal, and is used for TwinCAN and is output to the external system. The CPU clock fCPU and the system clock fSYS are derived from the master clock either directly (1:1) or via a 2:1 prescaler (fSYS = fCPU = fMC / 2). See also Section 5.1. The on-chip oscillator can drive an external crystal or accepts an external clock signal. The oscillator clock frequency can be multiplied by the on-chip PLL (by a programmable factor) or can be divided by a programmable prescaler factor. If the bypass mode is used (direct drive or prescaler) the PLL can deliver an independent clock to monitor the clock signal generated by the on-chip oscillator. This PLL clock is independent from the XTAL1 clock. When the expected oscillator clock transitions are missing the Oscillator Watchdog (OWD) activates the PLL Unlock / OWD interrupt node and supplies the CPU with an emergency clock, the PLL clock signal. Under these circumstances the PLL will oscillate with its basic frequency. The oscillator watchdog can be disabled by switching the PLL off. This reduces power consumption, but also no interrupt request will be generated in case of a missing oscillator clock. Note: At the end of an external reset (EA = `0') the oscillator watchdog may be disabled via hardware by (externally) pulling the RD line low upon a reset, similar to the standard reset configuration.
3.15
Parallel Ports
The XC164D provides up to 79 I/O lines which are organized into six input/output ports and one input port. All port lines are bit-addressable, and all input/output lines are individually (bit-wise) programmable as inputs or outputs via direction registers. The I/O ports are true bidirectional ports which are switched to high impedance state when configured as inputs. The output drivers of some I/O ports can be configured (pin by pin) for push/pull operation or open-drain operation via control registers. During the internal reset, all port pins are configured as inputs (except for pin RSTOUT). The edge characteristics (shape) and driver characteristics (output current) of the port drivers can be selected via registers POCONx. The input threshold of some ports is selectable (TTL or CMOS like), where the special CMOS like input threshold reduces noise sensitivity due to the input hysteresis. The input threshold may be selected individually for each byte of the respective ports. All port lines have programmable alternate input or output functions associated with them. All port lines that are not used for these alternate functions may be used as general purpose IO lines.

Power Management
The XC164D provides several means to control the power it consumes either at a given time or averaged over a certain timespan. Three mechanisms can be used (partly in parallel): * Power Saving Modes switch the XC164D into a special operating mode (control via instructions). Idle Mode stops the CPU while the peripherals can continue to operate. Sleep Mode and Power Down Mode stop all clock signals and all operation (RTC may optionally continue running). Sleep Mode can be terminated by external interrupt signals. Clock Generation Management controls the distribution and the frequency of internal and external clock signals. While the clock signals for currently inactive parts of logic are disabled automatically, the user can reduce the XC164D's CPU clock frequency which drastically reduces the consumed power. External circuitry can be controlled via the programmable frequency output FOUT. Peripheral Management permits temporary disabling of peripheral modules (control via register SYSCON3). Each peripheral can separately be disabled/enabled.
*

The on-chip RTC supports intermittend operation of the XC164D by generating cyclic wake-up signals. This offers full performance to quickly react on action requests while the intermittend sleep phases greatly reduce the average power consumption of the system.

The range limits may be reached under extreme operating conditions. However, specified parameters, such as leakage currents, refer to the standard operating voltage range of VDDP = 4.75 V to 5.25 V. 4) This limitation must be fulfilled under all operating conditions including power-ramp-up, power-ramp-down, and power-save modes.

5) Overload conditions occur if the standard operating conditions are exceeded, i.e. the voltage on any pin exceeds the specified range: VOV > VDDP + 0.5 V (IOV > 0) or VOV < VSS - 0.5 V (IOV < 0). The absolute sum of input overload currents on all pins may not exceed 50 mA. The supply voltages must remain within the specified limits. Proper operation is not guaranteed if overload conditions occur on functional pins such as XTAL1, RD, WR, etc. 6) Not subject to production test - verified by design/characterization. 7) An overload current (IOV) through a pin injects a certain error current (IINJ) into the adjacent pins. This error current adds to the respective pin's leakage current (IOZ). The amount of error current depends on the overload current and is defined by the overload coupling factor KOV. The polarity of the injected error current is inverse compared to the polarity of the overload current that produces it. The total current through a pin is |ITOT| = |IOZ| + (|IOV| x KOV). The additional error current may distort the input voltage on analog inputs. 8) The timing is valid for pin drivers operating in default current mode (selected after reset). Reducing the output current may lead to increased delays or reduced driving capability (CL).

For signal levels outside these specifications, also refer to the specification of the overload current IOV. 2) This parameter is tested for P2, P3, P4, P9. 3) The maximum deliverable output current of a port driver depends on the selected output driver mode, see Table 12, Current Limits for Port Output Drivers.

1) During Flash programming or erase operations the supply current is increased by max. 5 mA. 2) The supply current is a function of the operating frequency. This dependency is illustrated in Figure 11. These parameters are tested at VDDImax and maximum CPU clock frequency with all outputs disconnected and all inputs at VIL or VIH. 3) The pad supply voltage pins (VDDP) mainly provides the current consumed by the pin output drivers. A small amount of current is consumed even though no outputs are driven, because the drivers' input stages are switched and also the Flash module draws some power from the VDDP supply. 4) The total supply current in Sleep and Power-down mode is the sum of the temperature dependent leakage current and the frequency dependent current for RTC and main oscillator (if active).

5) This parameter is determined mainly by the transistor leakage currents. This current heavily depends on the junction temperature (see Figure 13). The junction temperature TJ is the same as the ambient temperature TA if no current flows through the port output drivers. Otherwise, the resulting temperature difference must be taken into account. 6) All inputs (including pins configured as inputs) at 0 V to 0.1 V or at VDDP - 0.1 V to VDDP, all outputs (including pins configured as outputs) disconnected. This parameter is tested at 25 C and is valid for TJ 25 C. 7) This parameter is determined mainly by the current consumed by the oscillator switched to low gain mode (see Figure 12). This current, however, is influenced by the external oscillator circuitry (crystal, capacitors). The given values refer to a typical circuitry and may change in case of a not optimized external oscillator circuitry.

Timing Parameters
Definition of Internal Timing
The internal operation of the XC164D is controlled by the internal master clock fMC. The master clock signal fMC can be generated from the oscillator clock signal fOSC via different mechanisms. The duration of master clock periods (TCMs) and their variation (and also the derived external timing) depend on the used mechanism to generate fMC. This influence must be regarded when calculating the timings for the XC164D.

Generation Mechanisms for the Master Clock
Note: The example for PLL operation shown in Figure 14 refers to a PLL factor of 1:4, the example for prescaler operation refers to a divider factor of 2:1. The used mechanism to generate the master clock is selected by register PLLCON. CPU and EBC are clocked with the CPU clock signal fCPU. The CPU clock can have the same frequency as the master clock (fCPU = fMC) or can be the master clock divided by two: fCPU = fMC / 2. This factor is selected by bit CPSYS in register SYSCON1. The specification of the external timing (AC Characteristics) depends on the period of the CPU clock, called "TCP". The other peripherals are supplied with the system clock signal fSYS which has the same frequency as the CPU clock signal fCPU.
Data Sheet 53 V1.0, 2005-01
XC164D Derivatives
Timing Parameters Bypass Operation When bypass operation is configured (PLLCTRL = 0xB) the master clock is derived from the internal oscillator (input clock signal XTAL1) through the input- and outputprescalers:
fMC = fOSC / ((PLLIDIV+1)x(PLLODIV+1)).
If both divider factors are selected as '1' (PLLIDIV = PLLODIV = '0') the frequency of fMC directly follows the frequency of fOSC so the high and low time of fMC is defined by the duty cycle of the input clock fOSC. The lowest master clock frequency is achieved by selecting the maximum values for both divider factors:
fMC = fOSC / ((3+1)x(14+1)) = fOSC / 60.
Phase Locked Loop (PLL) When PLL operation is configured (PLLCTRL = 11B) the on-chip phase locked loop is enabled and provides the master clock. The PLL multiplies the input frequency by the factor F (fMC = fOSC x F) which results from the input divider, the multiplication factor, and the output divider (F = PLLMUL+1 / (PLLIDIV+1 x PLLODIV+1)). The PLL circuit synchronizes the master clock to the input clock. This synchronization is done smoothly, i.e. the master clock frequency does not change abruptly. Due to this adaptation to the input clock the frequency of fMC is constantly adjusted so it is locked to fOSC. The slight variation causes a jitter of fMC which also affects the duration of individual TCMs. The timing listed in the AC Characteristics refers to TCPs. Because fCPU is derived from fMC, the timing must be calculated using the minimum TCP possible under the respective circumstances. The actual minimum value for TCP depends on the jitter of the PLL. As the PLL is constantly adjusting its output frequency so it corresponds to the applied input frequency (crystal or oscillator) the relative deviation for periods of more than one TCP is lower than for one single TCP (see formula and Figure 15). This is especially important for bus cycles using waitstates and e.g. for the operation of timers, serial interfaces, etc. For all slower operations and longer periods (e.g. pulse train generation or measurement, lower baudrates, etc.) the deviation caused by the PLL jitter is negligible. The value of the accumulated PLL jitter depends on the number of consecutive VCO output cycles within the respective timeframe. The VCO output clock is divided by the output prescaler (K = PLLODIV+1) to generate the master clock signal fMC. Therefore, the number of VCO cycles can be represented as K x N, where N is the number of consecutive fMC cycles (TCM).

V1.0, 2005-01
XC164D Derivatives
Timing Parameters For a period of N x TCM the accumulated PLL jitter is defined by the deviation DN: DN [ns] = (1.5 + 6.32 x N / fMC); fMC in [MHz], N = number of consecutive TCMs. So, for a period of 3 TCMs @ 20 MHz and K = 12: D3 = (1.5 + 6.32 x 3 / 20) = 2.448 ns. This formula is applicable for K x N < 95. For longer periods the KxN=95 value can be used. This steady value can be approximated by: DNmax [ns] = (1.5 + 600 / (K x fMC)).

Note: If the on-chip oscillator is used together with a crystal or a ceramic resonator, the oscillator frequency is limited to a range of 4 MHz to 16 MHz. It is strongly recommended to measure the oscillation allowance (negative resistance) in the final target system (layout) to determine the optimum parameters for the oscillator operation. Please refer to the limits specified by the crystal supplier. When driven by an external clock signal it will accept the specified frequency range. Operation at lower input frequencies is possible but is verified by design only (not subject to production test).

The duration of each cycle phase is programmable (via the TCONCSx registers) to adapt the external bus cycles to the respective external module (memory, peripheral, etc.). This table provides a summary of the phases and the respective choices for their duration.

Note: The bandwidth of a parameter (minimum and maximum value) covers the whole operating range (temperature, voltage) as well as process variations. Within a given device, however, this bandwidth is smaller than the specified range. This is also due to interdependencies between certain parameters.
