Ordering Information

The ordering code for Infineon microcontrollers provides an exact reference to the

required product. This ordering code identifies:

• the derivative itself, i.e. its function set, the temperature range, and the supply voltage

• the package and the type of delivery.

For the available ordering codes for the C164CM please refer to the “Product Catalog

Microcontrollers”, which summarizes all available microcontroller variants.

Note: The ordering codes for Mask-ROM versions are defined for each product after

verification of the respective ROM code.

Introduction

The C164CM derivatives of the Infineon C166 Family of full featured single-chip CMOS

microcontrollers are especially suited for cost sensitive applications. They combine high

CPU performance (up to 12.5 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 OTP, internal RAM, and

extension RAM.

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 C164CM 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.

An internal pullup resistor permits power-on reset using only

a capacitor connected to V_SS.

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.

In bidirectional reset mode (enabled by setting bit BDRSTEN

in register SYSCON) the RSTIN line is internally pulled low

for the duration of the internal reset sequence upon any reset

(HW, SW, WDT). See note below this table.

Note: To let the reset configuration of PORT0 settle and to

let the PLL lock a reset duration of ca. 1 ms is

recommended.

Note: The following behavior differences must be observed when the bidirectional reset

is active:

• Bit BDRSTEN in register SYSCON cannot be changed after EINIT and is cleared

automatically after a reset.

• The reset indication flags always indicate a long hardware reset.

• The PORT0 configuration is treated as if it were a hardware reset. In particular, the

bootstrap loader may be activated when P0L.4 is low.

• Pin RSTIN may only be connected to external reset devices with an open drain output

driver.

• A short hardware reset is extended to the duration of the internal reset sequence.

Functional Description

The architecture of the C164CM combines advantages of both RISC and CISC

processors and of advanced peripheral subsystems in a very well-balanced way. In

addition the on-chip memory blocks allow the design of compact systems with maximum

performance.

The following block diagram gives an overview of the different on-chip components and

of the advanced, high bandwidth internal bus structure of the C164CM.

Block Diagram

The program memory, the internal RAM (IRAM) and the set of generic peripherals are

connected to the CPU via separate buses. A fourth bus, the XBUS, connects external

resources as well as additional on-chip resoures, the X-Peripherals (see Figure 3).

The XBUS resources (CAN) of the C164CM can be enabled or disabled during

initialization by setting the general X-Peripheral enable bit XPEN (SYSCON.2). Modules

that are disabled consume neither address space nor port pins.

V1.0, 2001-05

C164CM

C164SM

Memory Organization

The memory space of the C164CM is configured in a Von Neumann architecture which

means that code memory, data memory, registers and I/O ports are organized within the

same linear address space which includes 16 MBytes. The entire memory space can be

accessed bytewise or wordwise. Particular portions of the on-chip memory have

additionally been made directly bitaddressable.

The C164CM incorporates 32 KBytes of on-chip OTP memory or on-chip mask-

programmable ROM (not in the ROM-less derivative, of course) for code or constant

data. The on-chip ROM/OTP can be mapped either to segment 0 or segment 1.

The OTP memory can be programmed by the CPU itself (in system, e.g. during booting)

or directly via an external interface (e.g. before assembly). The programming time is

approx. 100 µs per word. An external programming voltage V_PP= 11.5 V must be

supplied for this purpose (via pin EA/V_PP).

2 KBytes of on-chip Internal RAM (IRAM) are provided as a storage for user defined

variables, for the system stack, general purpose register banks and even for code. 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).

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 C166 Family.

In order to meet the needs of designs where more memory is required than is provided

on chip, up to 64 KBytes of external RAM and/or ROM can be connected to the

microcontroller.

Data Sheet

12

V1.0, 2001-05

C164CM

C164SM

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 two different external memory access modes, which are

as follows:

– 16-bit Addresses, 16-bit Data, Multiplexed

– 11-bit Addresses, 8-bit Data, Multiplexed

Both addresses and data use PORT0 for input/output.

Important timing characteristics of the external bus interface (Memory Cycle Time,

Memory Tri-State Time, Length of ALE and Read Write Delay) have been made

programmable 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 register pairs

ADDRSELx / BUSCONx) which control the access to different resources with different

bus characteristics. These address windows are arranged hierarchically where

BUSCON4 overrides BUSCON3 and BUSCON2 overrides BUSCON1. All accesses to

locations not covered by these 4 address windows are controlled by BUSCON0.

Note: The programmable bus features and the window mechanism are standard

features of the C166 architecture. Due to the C164CM’s limited external address

space, however, they can be utilized only to a small extend.

The C164CM will preferably be used in single-chip mode. Applications which require

access to external resources such as peripherals or small memories, will use the 8-bit

data bus with 11-bit address bus in most cases. In this case the upper pins of PORT0

can be used for the serial interfaces. If a wider address or a 16-bit data bus is required

the serial interfaces cannot be used.

V1.0, 2001-05

C164CM

C164SM

Central Processing Unit (CPU)

The main core of the CPU consists of a 4-stage instruction pipeline, a 16-bit arithmetic

and logic unit (ALU) and dedicated SFRs. Additional hardware has been spent for a

separate multiply and divide unit, a bit-mask generator and a barrel shifter.

Based on these hardware provisions, most of the C164CM’s instructions can be

executed in just one machine cycle which requires 2 CPU clocks (4 TCL). For example,

shift and rotate instructions are always processed during one machine cycle

independent of the number of bits to be shifted. All multiple-cycle instructions have been

optimized so that they can be executed very fast as well: branches in 2 cycles, a

16 × 16 bit multiplication in 5 cycles and a 32-/16-bit division in 10 cycles. Another

pipeline optimization, the so-called ‘Jump Cache’, reduces the execution time of

repeatedly performed jumps in a loop from 2 cycles to 1 cycle.

C164CM

C164SM

The CPU has a register context consisting of up to 16 wordwide GPRs at its disposal.

These 16 GPRs are physically allocated within the on-chip RAM 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 1024 words is provided as a storage for temporary data. The

system stack is allocated 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 C164CM instruction set which

includes the following instruction classes:

– 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.

C164SM

Interrupt System

With an interrupt response time within a range from just 5 to 12 CPU clocks (in case of

internal program execution), the C164CM is capable of reacting very fast to the

occurrence of non-deterministic events.

The architecture of the C164CM 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. An individual PEC transfer

counter is implicity 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 C164CM 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 sources. Via

its related register, each source 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 sources 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 3 shows all of the possible C164CM interrupt sources and the corresponding

hardware-related interrupt flags, vectors, vector locations and trap (interrupt) numbers.

Note: Interrupt nodes which are not used by associated peripherals, may be used to

generate software controlled interrupt requests by setting the respective interrupt

request bit (xIR).

The C164CM 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.

The Capture/Compare Unit CAPCOM2

The general purpose CAPCOM2 unit supports generation and control of timing

sequences on up to 12 channels with a maximum resolution of 16 TCL. 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.

Two 16-bit timers (T7/T8) with reload registers provide two independent time bases for

the capture/compare register array.

Each dual purpose capture/compare register, which may be individually allocated to

either CAPCOM timer and programmed for capture or compare function, has 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.

When a capture/compare register has been selected for capture mode, the current

contents of the allocated timer will be latched (‘capture’d) 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 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. 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 12 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 CPU clock.

General Purpose Timer (GPT) Unit

The GPT 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 GPT unit incorporates three 16-bit timers. Each timer may operate independently in

a number of different modes, or may be concatenated with another timer.

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 CPU 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 16 TCL.

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-

flow/underflow. The state of this latch may 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.

Real Time Clock

The Real Time Clock (RTC) module of the C164CM consists of a chain of 3 divider

blocks, a fixed 8:1 divider, the reloadable 16-bit timer T14, and the 32-bit RTC timer

(accessible via registers RTCH and RTCL). The RTC module is directly clocked with the

on-chip oscillator frequency divided by 32 via a separate clock driver (f_RTC= f_OSC/32)

and is therefore independent from the selected clock generation mode of the C164CM.

All timers count up.

The RTC module can be used for different purposes:

• System clock to determine the current time and date

• Cyclic time based interrupt

• 48-bit timer for long term measurements

A/D Converter

For analog signal measurement, a 10-bit A/D converter with 8 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 and can so be adjusted to the external circuitry.

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 than 8 analog input channels, the remaining channel

inputs can be used as digital input port pins.

The A/D converter of the C164CM 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 (standard or extension) are sequentially sampled and converted. In

the Auto Scan Continuous mode, the number of prespecified channels is 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).

Serial Channels

Serial communication with other microcontrollers, processors, terminals or external

peripheral components is provided by two serial interfaces with different functionality, an

Asynchronous/Synchronous Serial Channel (ASC0) and a High-Speed Synchronous

Serial Channel (SSC).

The ASC0 is upward compatible with the serial ports of the Infineon 8-bit microcontroller

families and supports full-duplex asynchronous communication at up to 781 Kbit/s and

half-duplex synchronous communication at up to 3.1 Mbit/s (@ 25 MHz CPU clock).

A dedicated baud rate generator allows to set up all standard baud rates without

oscillator tuning. For transmission, reception and error handling 4 separate interrupt

vectors are provided. In asynchronous mode, 8- or 9-bit data frames 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).

In synchronous mode, the ASC0 transmits or receives bytes (8 bits) synchronously to a

shift clock which is generated by the ASC0. The ASC0 always shifts the LSB first. A loop

back option is available for testing purposes.

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.

The SSC supports full-duplex synchronous communication at up to 6.25 Mbit/s

(@ 25 MHz CPU clock). It may be configured so it interfaces with serially linked

peripheral components. A dedicated baud rate generator allows to set up all standard

baud rates without oscillator tuning. For transmission, reception and error handling

3 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 and receive error supervise the correct handling

of the data buffer. Phase and baudrate error detect incorrect serial data.

CAN-Module

The integrated CAN-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 CAN-Modules can receive and transmit standard frames with 11-bit

identifiers as well as extended frames with 29-bit identifiers.

The module provides Full CAN functionality on up to 15 message objects. Message

object 15 may be configured for Basic CAN functionality. Both modes provide separate

masks for acceptance filtering which allows to accept a number of identifiers in Full CAN

mode and also allows to disregard a number of identifiers in Basic CAN mode. All

message objects can be updated independent from the other objects and are equipped

for the maximum message length of 8 bytes.

The bit timing is derived from the XCLK and is programmable up to a data rate of 1 Mbit/

s. Each CAN-Module uses two pins of Port 4 or Port 8 to interface to an external bus

transceiver. The interface pins are assigned via software.

Note: When the CAN interface is assigned to Port 8, the respective CAPCOM IO lines

on Port 8 cannot be used.

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 only be

disabled in the time interval until the EINIT (end of initialization) instruction has been

executed. Thus, the chip’s start-up procedure is always monitored. The software has to

be designed to service 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. Thus, time intervals between 20 µs and 336 ms can be

monitored (@ 25 MHz).

The default Watchdog Timer interval after reset is 5.24 ms (@ 25 MHz).

Parallel Ports

The C164CM provides up to 50 I/O lines which are organized into four 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 Port 8 can be configured (pin by pin) for push/

pull operation or open-drain operation via a control register. During the internal reset, all

port pins are configured as inputs.

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.

PORT0 may be used as address and data lines when accessing external memory. Also

the serial interfaces ASC0 and SSC use the upper pins of P0H.

Ports P1L, P1H, and P8 are associated with the capture inputs or compare outputs of

the CAPCOM units and/or serve as external interrupt inputs.

Port 5 is used for the analog input channels to the A/D converter or timer control signals.

Port 20 includes the bus control signals RD, WR, ALE, the configuration input EA, the

the system control output RSTOUT, and the system clock output CLKOUT (or the

programmable frequency output FOUT).

The edge characteristics (transition time) and driver characteristics (output current) of

the C164CM’s port drivers can be selected via the Port Output Control registers

(POCONx).

Oscillator Watchdog

The Oscillator Watchdog (OWD) monitors the clock signal generated by the on-chip

oscillator (either with a crystal or via external clock drive). For this operation the PLL

provides a clock signal which is used to supervise transitions on the oscillator clock. This

PLL clock is independent from the XTAL1 clock. When the expected oscillator clock

transitions are missing the OWD activates the PLL Unlock/OWD interrupt node and

supplies the CPU with the PLL clock signal. Under these circumstances the PLL will

oscillate with its basic frequency.

In direct drive mode the PLL base frequency is used directly (f_CPU= 2 … 5 MHz).

In prescaler mode the PLL base frequency is divided by 2 (f_CPU= 1 … 2.5 MHz).

Note: The CPU clock source is only switched back to the oscillator clock after a

hardware reset.

The oscillator watchdog can be disabled by setting bit OWDDIS in register SYSCON.

In this case (OWDDIS = ‘1’) the PLL remains idle and provides no clock signal, while the

CPU clock signal is derived directly from the oscillator clock or via prescaler or SDD. Also

no interrupt request will be generated in case of a missing oscillator clock.

Note: At the end of a reset bit OWDDIS reflects the inverted level of pin RD at that time.

Thus the oscillator watchdog may also be disabled via hardware by (externally)

pulling the RD line low upon a reset, similar to the standard reset configuration via

PORT0.

C164CM

C164SM

Power Management

The C164CM 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 C164CM 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 (control via register SYSCON2).

Slow Down Mode lets the C164CM run at a CPU clock frequency of f_OSC/1 … 32 (half

for prescaler operation) which drastically reduces the consumed power. The PLL can

be optionally disabled while operating in Slow Down Mode.

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. A group control option disables

a major part of the peripheral set by setting one single bit.

The on-chip RTC supports intermittend operation of the C164CM by generating cyclic

wakeup 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.

Special Function Registers Overview

Table 7 lists all SFRs which are implemented in the C164CM in alphabetical order.

Bit-addressable SFRs are marked with the letter “b” in column “Name”. SFRs within the

Extended SFR-Space (ESFRs) are marked with the letter “E” in column “Physical

Address”. Registers within on-chip X-peripherals are marked with the letter “X” in column

“Physical Address”.

An SFR can be specified via its individual mnemonic name. Depending on the selected

addressing mode, an SFR can be accessed via its physical address (using the Data

Page Pointers), or via its short 8-bit address (without using the Data Page Pointers).

AC Characteristics

Definition of Internal Timing

The internal operation of the C164CM is controlled by the internal CPU clock f_CPU. Both

edges of the CPU clock can trigger internal (e.g. pipeline) or external (e.g. bus cycles)

operations.

The specification of the external timing (AC Characteristics) therefore depends on the

time between two consecutive edges of the CPU clock, called “TCL” (see Figure 11).

Generation Mechanisms for the CPU Clock

The CPU clock signal f_CPUcan be generated from the oscillator clock signal f_OSCvia

different mechanisms. The duration of TCLs and their variation (and also the derived

external timing) depends on the used mechanism to generate f_CPU. This influence must

be regarded when calculating the timings for the C164CM.

Note: The example for PLL operation shown in Figure 11 refers to a PLL factor of 4.

The used mechanism to generate the basic CPU clock is selected by bitfield CLKCFG

in register RP0H.7-5.

Upon a long hardware reset register RP0H is loaded with the logic levels present on the

upper half of PORT0 (P0H), i.e. bitfield CLKCFG represents the logic levels on pins

Please note that pin P0.15 (corresponding to RP0H.7) is inverted in emulation mode, and thus also in EHM.

The external clock input range refers to a CPU clock range of 10 … 25 MHz.

The maximum frequency depends on the duty cycle of the external clock signal.

Prescaler Operation

When prescaler operation is configured (CLKCFG = 001 ) the CPU clock is derived from

B

the internal oscillator (input clock signal) by a 2:1 prescaler.

The frequency of f_CPUis half the frequency of f_OSCand the high and low time of f_CPU(i.e.

the duration of an individual TCL) is defined by the period of the input clock f_OSC

.

The timings listed in the AC Characteristics that refer to TCLs therefore can be

calculated using the period of f_OSCfor any TCL.

Phase Locked Loop

When PLL operation is configured (via CLKCFG) the on-chip phase locked loop is

enabled and provides the CPU clock (see Table 11). The PLL multiplies the input

frequency by the factor F which is selected via the combination of pins P0.15-13 (i.e.

f_CPU= f_OSC× F). With every F’th transition of f_OSCthe PLL circuit synchronizes the CPU

clock to the input clock. This synchronization is done smoothly, i.e. the CPU clock

frequency does not change abruptly.

Data Sheet

49

V1.0, 2001-05

C164CM

C164SM

Due to this adaptation to the input clock the frequency of f_CPUis constantly adjusted so

it is locked to f_OSC. The slight variation causes a jitter of f_CPUwhich also effects the

duration of individual TCLs.

The timings listed in the AC Characteristics that refer to TCLs therefore must be

calculated using the minimum TCL that is possible under the respective circumstances.

The actual minimum value for TCL 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 TCL is lower than

for one single TCL (see formula and Figure 12).

For a period of N × TCL the minimum value is computed using the corresponding

deviation D :

N

(N × TCL)

= N × TCL

- D ; D [ns] = (13.3 + N × 6.3)/f_CPU[MHz],

NOM

N N

min

where N = number of consecutive TCLs and 1 ≤ N ≤ 40.

So for a period of 3 TCLs @ 25 MHz (i.e. N = 3): D = (13.3 + 3 × 6.3)/25 = 1.288 ns,

3

and (3TCL)

= 3TCL

- 1.288 ns = 58.7 ns (@ f_CPU= 25 MHz).

min

NOM

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 neglectible.

Note: For all periods longer than 40 TCL the N = 40 value can be used (see Figure 12).

Direct Drive

When direct drive is configured (CLKCFG = 011 ) the on-chip phase locked loop is

B

disabled and the CPU clock is directly driven from the internal oscillator with the input

clock signal.

The frequency of f_CPUdirectly follows the frequency of f_OSCso the high and low time of

f_CPU(i.e. the duration of an individual TCL) is defined by the duty cycle of the input clock

f_OSC

.

The timings listed below that refer to TCLs therefore must be calculated using the

minimum TCL that is possible under the respective circumstances. This minimum value

can be calculated via the following formula:

TCL

= 1/f_OSC× DC

(DC = duty cycle)

min

For two consecutive TCLs the deviation caused by the duty cycle of f_OSCis compensated

so the duration of 2TCL is always 1/f_OSC. The minimum value TCL therefore has to

min

be used only once for timings that require an odd number of TCLs (1, 3, …). Timings that

require an even number of TCLs (2, 4, …) may use the formula 2TCL = 1/f_OSC

.

Note: If the on-chip oscillator is used together with a crystal, the oscillator frequency is

limited to a range of 4 MHz to 16 MHz.

It is strongly recommended to measure the oscillation allowance (or margin) 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 guaranteed by

Notes

1)

Cycle as programmed, including MCTC waitstates (Example shows 0 MCTC WS).

The leading edge of the respective command depends on RW-delay.

2)

3)

Multiplexed bus modes have a MUX waitstate added after a bus cycle, and an additional MTTC waitstate may

be inserted here.

For a multiplexed bus with MTTC waitstate this delay is 2 CLKOUT cycles.

The next external bus cycle may start here.

Infineon goes for Business Excellence

“Business excellence means intelligent approaches and clearly

defined processes, which are both constantly under review and

ultimately lead to good operating results.

Better operating results and business excellence mean less

idleness and wastefulness for all of us, more professional

success, more accurate information, a better overview and,

thereby, less frustration and more satisfaction.”

Dr. Ulrich Schumacher
