Introduction
The XC164 derivatives are high-performance members of the Infineon XC166 Family of
full featured single-chip CMOS microcontrollers. These devices extend the functionality
and performance of the C166 Family in terms of instructions (MAC unit), peripherals, and
speed. They combine high CPU performance (up to 40 million instructions per second)
with high peripheral functionality and enhanced IO-capabilities. They also provide clock
generation via PLL and various on-chip memory modules such as program ROM or
Flash, program RAM, and data RAM.

I
Reset Input with Schmitt-Trigger characteristics. A low level
at this pin while the oscillator is running resets the XC164.
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.

For details, please refer to the description of P20.
NMI
3
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 XC164 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.

Functional Description
The architecture of the XC164 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 resources 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 XC164.
The following block diagram gives an overview of the different on-chip components and
of the advanced, high bandwidth internal bus structure of the XC164.

3.1
Memory Subsystem and Organization
The memory space of the XC164 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 on-
chip 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, ROM, 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.
64/128 Kbytes1) of on-chip Flash memory or mask-programmable ROM store code
or constant data. The on-chip Flash memory is organized as four 8-Kbyte sectors, one
32-Kbyte sector, and one 64-Kbyte sector. Each sector can be separately write
protected2), erased and programmed (in blocks of 128 Bytes). The complete Flash or
ROM 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.
For timing characteristics, please refer to Section 4.4.2.
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.
2/4 Kbytes1) 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, and general purpose register banks. A register

bank can consist of up to 16 wordwide (R0 to R15) and/or bytewide (RL0, RH0, …, RL7,
RH7) 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 × 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.

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.
Note: The chip select signal of address window 4 is not available on a pin.
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 XC164’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 division algorithm is performed in 18 to 21
CPU cycles, depending on the data and division type. Four cycles are always visible, the
rest runs in the 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. The global register bank is physically allocated within the on-
chip DPRAM area. A Context Pointer (CP) register determines the base address of the
active global 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 XC164 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 XC164 is capable of reacting very fast to the occurrence of non-
deterministic events.
The architecture of the XC164 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 XC164 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 XC164 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).

Functional Description
The XC164 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 occurrence of a
hardware trap is additionally signified by an individual bit in the trap flag register (TFR).
Except when another higher prioritized trap service is in progress, a hardware trap will
interrupt any actual program execution. In turn, hardware trap services can normally not
be interrupted by standard or PEC interrupts.
Table 5 shows all of the possible exceptions or error conditions that can arise during run-
time:

On-Chip Debug Support (OCDS)
The On-Chip Debug Support system provides a broad range of debug and emulation
features built into the XC164. The user software running on the XC164 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.

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.

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 over-
flowoverflow/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

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
after the capture procedure. This allows the XC164 to measure absolute time differences
or to perform pulse multiplication without software overhead.
The capture trigger (timer T5 to CAPREL) may also be generated upon transitions of
GPT1 timer T3’s inputs T3IN and/or T3EUD. This is especially advantageous when T3
operates in Incremental Interface Mode.

Real Time Clock
The Real Time Clock (RTC) module of the XC164 is directly clocked via a separate clock
driver with the prescaled on-chip main oscillator frequency (fRTC = fOSCm/32). It is
therefore independent from the selected clock generation mode of the XC164.
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.

A/D Converter
For analog signal measurement, a 10-bit A/D converter with 14 multiplexed input
channels and a sample and hold circuit has been integrated on-chip. It uses the method
of successive approximation. The sample time (for loading the capacitors) and the
conversion time is programmable (in two modes) and can thus be adjusted to the
external circuitry. The A/D converter can also operate in 8-bit conversion mode, where
the conversion time is further reduced.
Overrun error detection/protection is provided for the conversion result register
(ADDAT): either an interrupt request will be generated when the result of a previous
conversion has not been read from the result register at the time the next conversion is
complete, or the next conversion is suspended in such a case until the previous result
has been read.
For applications which require less analog input channels, the remaining channel inputs
can be used as digital input port pins.
The A/D converter of the XC164 supports four different conversion modes. In the
standard Single Channel conversion mode, the analog level on a specified channel is
sampled once and converted to a digital result. In the Single Channel Continuous mode,
the analog level on a specified channel is repeatedly sampled and converted without
software intervention. In the Auto Scan mode, the analog levels on a prespecified
number of channels are sequentially sampled and converted. In the Auto Scan
Continuous mode, the prespecified channels are repeatedly sampled and converted. In
addition, the conversion of a specific channel can be inserted (injected) into a running
sequence without disturbing this sequence. This is called Channel Injection Mode.
The Peripheral Event Controller (PEC) may be used to automatically store the
conversion results into a table in memory for later evaluation, without requiring the
overhead of entering and exiting interrupt routines for each data transfer.
After each reset and also during normal operation the ADC automatically performs
calibration cycles. This automatic self-calibration constantly adjusts the converter to
changing operating conditions (e.g. temperature) and compensates process variations.
These calibration cycles are part of the conversion cycle, so they do not affect the normal
operation of the A/D converter.
In order to decouple analog inputs from digital noise and to avoid input trigger noise
those pins used for analog input can be disconnected from the digital IO or input stages
under software control. This can be selected for each pin separately via register P5DIDIS
(Port 5 Digital Input Disable).
The Auto-Power-Down feature of the A/D converter minimizes the power consumption
when no conversion is in progress.

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 half-
duplex 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

High Speed Synchronous Serial Channels (SSC0/SSC1)
The High Speed Synchronous Serial Channels SSC0/SSC1 support full-duplex and half-
duplex 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

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 FIFO-
structures. 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, Port 7, 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 µs 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 XC164 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 4.4.1.
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.
3.16
Parallel Ports
The XC164 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 XC164 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 XC164 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 XC164’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 intermittent operation of the XC164 by generating cyclic
wake-up signals. This offers full performance to quickly react on action requests while
the intermittent sleep phases greatly reduce the average power consumption of the
system.

3) The specified voltage range is allowed for operation. The range limits may be reached under extreme
operating conditions. However, specified parameters, such as leakage currents, refer to the standard

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| × 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).

and partly its demands on the system. To aid in interpreting the parameters right, when
evaluating them for a design, they are marked in column “Symbol”:

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

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.

If the analog reference supply voltage drops below 4.5 V (i.e. VAREF ≥ 4.0 V) or exceeds the power supply

Definition of Internal Timing
The internal operation of the XC164 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 XC164.

Generation Mechanisms for the Master Clock
Note: The example for PLL operation shown in Figure 15 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.
Data Sheet
62
V2.2, 2006-03
XC164-16
Derivatives
Electrical Parameters
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
.
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 output-
prescalers:
fMC = fOSC / ((PLLIDIV+1) × (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) × (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 × F) which results from the input divider, the multiplication factor, and
the output divider (F = PLLMUL+1 / (PLLIDIV+1 × 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 16).
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
Data Sheet
63
V2.2, 2006-03
XC164-16
Derivatives
Electrical Parameters
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 × N, where N is the number of
consecutive fMC cycles (TCM).
For a period of N × TCM the accumulated PLL jitter is defined by the deviation DN:
DN [ns] = ±(1.5 + 6.32 × 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 × 3 / 20) = 2.448 ns.
This formula is applicable for K × N < 95. For longer periods the K × N = 95 value can be
used. This steady value can be approximated by: DNmax [ns] = ±(1.5 + 600 / (K × fMC)).

On-chip Flash Operation
The XC164’s Flash module delivers data within a fixed access time (see Table 17).
Accesses to the Flash module are controlled by the PMI and take 1+WS clock cycles,
where WS is the number of Flash access waitstates selected via bitfield WSFLASH in
register IMBCTRL. The resulting duration of the access phase must cover the access
time tACC of the Flash array. Therefore, the required Flash waitstates depend on the
available speed grade as well as on the actual system frequency.
Note: The Flash access waitstates only affect non-sequential accesses. Due to
prefetching mechanisms, the performance for sequential accesses (depending on
the software structure) is only partially influenced by waitstates.
In typical applications, eliminating one waitstate increases the average
performance by 5% … 15%.

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).
