RSTIN
I/O
Reset Input with Schmitt-Trigger characteristics. A low level
at this pin while the oscillator is running resets the C167CS3V. An internal pullup resistor permits power-on reset using
only a capacitor connected to VSS.
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.

The architecture of the C167CS-3V 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 C167CS-3V.

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 (XRAM, CAN) of the C167CS-3V can be individually enabled or
disabled during initialization. Register XPERCON selects the required modules which
are then enabled by setting the general X-Peripheral enable bit XPEN (SYSCON.2).
Modules that are disabled consume neither address space nor port pins.
Note: The default value of register XPERCON after reset selects 2 KByte XRAM and
module CAN1, so the default XBUS resources are compatible with the C167CR.

Memory Organization
The memory space of the C167CS-3V 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.
3 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.
8 KBytes of on-chip Extension RAM (XRAM), organized as two blocks of 2 KByte and
6 KByte, respectively, are provided to store user data, user stacks, or code. The XRAM
is accessed like external memory and therefore cannot be used for the system stack or
for register banks and is not bitaddressable. The XRAM permits 16-bit accesses with
maximum speed.
In order to meet the needs of designs where more memory is required than is provided
on chip, up to 16 MBytes 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 modes, which are
as follows:
–
–
–
–
16-/18-/20-/24-bit Addresses, 16-bit Data, Demultiplexed
16-/18-/20-/24-bit Addresses, 16-bit Data, Multiplexed
16-/18-/20-/24-bit Addresses, 8-bit Data, Multiplexed
16-/18-/20-/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.
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.
Up to 5 external CS signals (4 windows plus default) can be generated in order to save
external glue logic. The C167CS-3V offers the possibility to switch the CS outputs to an
unlatched mode. In this mode the internal filter logic is switched off and the CS signals
are directly generated from the address. The unlatched CS mode is enabled by setting
CSCFG (SYSCON.6).
Access to very slow memories or memories with varying access times is supported via
a particular ‘Ready’ function.
A HOLD/HLDA protocol is available for bus arbitration and allows to share external
resources with other bus masters. The bus arbitration is enabled by setting bit HLDEN
in register PSW. After setting HLDEN once, pins P6.7 … P6.5 (BREQ, HLDA, HOLD)
are automatically controlled by the EBC. In Master Mode (default after reset) the HLDA
pin is an output. By setting bit DP6.7 to ‘1’ the Slave Mode is selected where pin HLDA
is switched to input. This allows to directly connect the slave controller to another master
controller without glue logic.
For applications which require less than 16 MBytes of external memory space, this
address space can be restricted to 1 MByte, 256 KByte, or to 64 KByte. In this case
Port 4 outputs four, two, or no address lines at all. It outputs all 8 address lines, if an
address space of 16 MBytes is used.

Low Power
Note: When one or both of the on-chip CAN Modules are used with the interface lines
assigned to Port 4, the CAN lines override the segment address lines and the
segment address output on Port 4 is therefore limited to 6/4 bits i.e. address lines
A21/A19 … A16. CS lines can be used to increase the total amount of
addressable external memory.
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 C167CS-3V’s instructions can be
executed in just one machine cycle which requires 50 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. 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’, allows reducing the execution time of
repeatedly performed jumps in a loop from 2 cycles to 1 cycle.

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 C167CS-3V instruction set which

Interrupt System
With an interrupt response time within a range from just 5 to 12 CPU clocks (in case of
internal program execution), the C167CS-3V is capable of reacting very fast to the
occurrence of non-deterministic events.
The architecture of the C167CS-3V 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 C167CS-3V 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 C167CS-3V 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).

C167CS-L16M3V
Low Power
The C167CS-3V 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). 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 4 shows all of the possible exceptions or error conditions that can arise during runtime:

Capture/Compare (CAPCOM) Units
The CAPCOM units support generation and control of timing sequences on up to
32 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.
Four 16-bit timers (T0/T1, T7/T8) with reload registers provide two independent time
bases for the 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.
Each register 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.

PWM Module
The Pulse Width Modulation Module can generate up to four PWM output signals using
edge-aligned or center-aligned PWM. In addition the PWM module can generate PWM
burst signals and single shot outputs. The frequency range of the PWM signals covers
2 Hz to 8 MHz (referred to a CPU clock of 16 MHz), depending on the resolution of the
PWM output signal. The level of the output signals is selectable and the PWM module
can generate interrupt requests.

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 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 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 overflow/underflow. The state of this latch may be output on pin T3OUT e.g. for time out
monitoring of external hardware components, or 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. 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.

Block Diagram of GPT1
With its maximum resolution of 8 TCL, 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
CAPCOM timers T0 or T1, 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

differences or to perform pulse multiplication without software overhead.
The capture trigger (timer T5 to CAPREL) may also be generated upon transitions of

operates in Incremental Interface Mode.

Real Time Clock
The Real Time Clock (RTC) module of the C167CS-3V 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 (fRTC = fOSC/32)
and is therefore independent from the selected clock generation mode of the C167CS3V. 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 24 multiplexed input
channels (16 standard channels and 8 extension 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 24 analog input channels, the remaining
channel inputs can be used as digital input port pins.
The A/D converter of the C167CS-3V 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 registers
P5DIDIS (Port 5 Digital Input Disable) and P1DIDIS (PORT1 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 500 KBaud and
half-duplex synchronous communication at up to 2.0 MBaud (@ 16 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 4.0 MBaud
(@ 16 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-Modules
The integrated CAN-Modules handle 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 modules provide Full CAN functionality on up to 15 message objects each. 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 MBaud. 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.
Module CAN2 is identical with the first one, except that it uses a separate address area
and a separate interrupt node.
The two CAN modules can be internally coupled by assigning their interface pins to the
same two port pins, or they can interface to separate CAN buses.
Note: When any CAN interface is assigned to Port 4, the respective segment address
lines on Port 4 cannot be used. This will limit the external address space.
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 32 µs and 1049 ms can be
monitored (@ 16 MHz).
The default Watchdog Timer interval after reset is 8.2 ms (@ 16 MHz).

Parallel Ports
The C167CS-3V provides up to 111 I/O lines which are organized into eight 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 five 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.
The input threshold of Port 2, Port 3, Port 7, and Port 8 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.
PORT0 and PORT1 may be used as address and data lines when accessing external
memory, while Port 4 outputs the additional segment address bits A23/19/17 … A16 in
systems where segmentation is enabled to access more than 64 KBytes of memory.
Port 2, Port 8 and Port 7 (and parts of PORT1) are associated with the capture inputs or
compare outputs of the CAPCOM units and/or with the outputs of the PWM module.
Port 6 provides optional bus arbitration signals (BREQ, HLDA, HOLD) and chip select
signals.
Port 3 includes alternate functions of timers, serial interfaces, the optional bus control
signal BHE/WRH, and the system clock output CLKOUT (or the programmable
frequency output FOUT).
Port 5 (and parts of PORT1) is used for the analog input channels to the A/D converter
or timer control signals.
The edge characteristics (transition time) and driver characteristics (output current) of
the C167CS-3V’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 (fCPU = 2 … 5 MHz).
In prescaler mode the PLL base frequency is divided by 2 (fCPU = 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.

Power Management
The C167CS-3V 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 C167CS-3V 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 C167CS-3V run at a CPU clock frequency of fOSC/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 C167CS-3V 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 C167CS-3V 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 C167CS-3V is controlled by the internal CPU clock fCPU.
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 fCPU can be generated from the oscillator clock signal fOSC via
different mechanisms. The duration of TCLs and their variation (and also the derived
external timing) depends on the used mechanism to generate fCPU. This influence must
be regarded when calculating the timings for the C167CS-3V.
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

P0.15-13 (P0H.7-5). Register RP0H can be loaded from the upper half of register
RSTCON under software control.

generation mode.

1)
The external clock input range refers to a CPU clock range of 10 … 16 MHz.
2)
The maximum frequency depends on the duty cycle of the external clock signal.
Prescaler Operation
When prescaler operation is configured (CLKCFG=001B) the CPU clock is derived from
the internal oscillator (input clock signal) by a 2:1 prescaler.
The frequency of fCPU is half the frequency of fOSC and the high and low time of fCPU (i.e.
the duration of an individual TCL) is defined by the period of the input clock fOSC.
The timings listed in the AC Characteristics that refer to TCLs therefore can be
calculated using the period of fOSC for 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 above). The PLL multiplies the input
frequency by the factor F which is selected via the combination of pins P0.15-13 (i.e.
fCPU = fOSC × F). With every F’th transition of fOSC the 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.
Due to this adaptation to the input clock the frequency of fCPU is constantly adjusted so
it is locked to fOSC. The slight variation causes a jitter of fCPU which also effects the
duration of individual TCLs.
Data Sheet
56
V1.0, 2001-10
C167CS-L16M3V
Low Power
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 DN:
(N × TCL)min = N × TCLNOM - DN; DN [ns] = ±(13.3 + N × 6.3) / fCPU [MHz],
where N = number of consecutive TCLs and 1 ≤ N ≤ 40.
So for a period of 3 TCLs @ 25 MHz (i.e. N = 3): D3 = (13.3 + 3 × 6.3) / 25 = 1.288 ns,
and (3TCL)min = 3TCLNOM - 1.288 ns = 58.7 ns (@ fCPU = 25 MHz).
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).

Low Power
Direct Drive
When direct drive is configured (CLKCFG = 011B) the on-chip phase locked loop is
disabled and the CPU clock is directly driven from the internal oscillator with the input
clock signal.
The frequency of fCPU directly follows the frequency of fOSC so the high and low time of
fCPU (i.e. the duration of an individual TCL) is defined by the duty cycle of the input clock
fOSC.
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:
TCLmin = 1/fOSC × DCmin
(DC = duty cycle)
For two consecutive TCLs the deviation caused by the duty cycle of fOSC is compensated
so the duration of 2TCL is always 1/fOSC. The minimum value TCLmin therefore has to
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/fOSC.

The minimum and maximum oscillator periods for PLL operation depend on the selected CPU clock generation
mode. Please see respective table above.
2)
The clock input signal must reach the defined levels VIL2 and VIH2.
3)
The minimum high and low time refers to a duty cycle of 50%. The maximum operating frequency (fCPU) in
direct drive mode depends on the duty cycle of the clock input signal.

Note: If the on-chip oscillator is used together with a crystal, the oscillator frequency is
limited to a range of 4 MHz to 25 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
design only (not 100% tested).

TUE is tested at VAREF = 3.3 V, VAGND = 0 V, VDD = 3.2 V. It is guaranteed by design for all other voltages
within the defined voltage range.
If the analog reference supply voltage exceeds the power supply voltage by up to 0.2 V
(i.e. VAREF = VDD = +0.2 V) the maximum TUE is increased to ±5/11 LSB. This range is not 100% tested.
The specified TUE is guaranteed only if the absolute sum of input overload currents on Port 5 pins and P1H
pins (see IOV specification) does not exceed 10 mA.
During the reset calibration sequence the maximum TUE may be ±8 LSB (±12 LSB for channels 16 … 23).
2)
VAIN may exceed VAGND or VAREF up to the absolute maximum ratings. However, the conversion result in
these cases will be X000H or X3FFH, respectively.
3)
The limit values for fBC must not be exceeded when selecting the CPU frequency and the ADCTC setting.
4)
This parameter includes the sample time tS, the time for determining the digital result and the time to load the
result register with the conversion result.
Values for the basic clock tBC depend on programming and can be taken from Table 14.
This parameter depends on the ADC control logic. It is not a real maximum value, but rather a fixum.
5)
During the conversion the ADC’s capacitance must be repeatedly charged or discharged. The internal
resistance of the reference voltage source must allow the capacitance to reach its respective voltage level
within each conversion step. The maximum internal resistance results from the programmed conversion
timing.

During the sample time the input capacitance CAIN can be charged/discharged by the external source. The
internal resistance of the analog source must allow the capacitance to reach its final voltage level within tS.
After the end of the sample time tS, changes of the analog input voltage have no effect on the conversion result.
Values for the sample time tS depend on programming and can be taken from Table 14.
Sample time and conversion time of the C167CS-3V’s A/D Converter are programmable.
Table 14 should be used to calculate the above timings.

The CLKOUT cycle time is influenced by the PLL jitter (given value applies to fCPU = 16 MHz).
For a single CLKOUT cycle (2 TCL) the deviation caused by the PLL jitter is below 1.6 ns (for fCPU = 16 MHz).
For longer periods the relative deviation decreases (see PLL deviation formula).

Read data are latched with the same (internal) clock edge that triggers the address change and the rising edge
of RD. Therefore address changes before the end of RD have no impact on (demultiplexed) read cycles.

Due to comparable propagation delays the address does not change before WR goes high. The minimum
output delay (tc17min) is therefore the actual value of tc12.

The rising edge of signal WR/WRH/WRL/WrCS is controlled by the early write feature (bit BUSCON.EWENx).
A bus cycle is extended here, if MCTC waitstates are selected or if the READY input is sampled inactive.
A bus cycle is extended here, if an MTTC waitstate is selected.

Bus Cycle Control via READY Input
The duration of an external bus cycle can be controlled by the external circuitry via the
READY input signal.
Synchronous READY permits the shortest possible bus cycle but requires the input
signal to be synchronous to the reference signal CLKOUT.
Asynchronous READY puts no timing constraints on the input signal but incurs one
waitstate minimum due to the additional synchronization stage.

1)
Cycle as programmed, including MCTC waitstates (Example shows 0 MCTC WS).
2) 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, for a
demultiplexed bus without MTTC waitstate this delay is zero.
3)
These timings are given for test purposes only, in order to assure recognition at a specific clock edge.
If the Asynchronous READY signal does not fulfill the indicated setup and hold times with respect to CLKOUT,
it must fulfill tc27 in order to be safely synchronized.
Proper deactivation of READY is guaranteed if READY is deactivated in response to the trailing (rising) edge
of the corresponding command (RD or WR).
4)
READY sampled HIGH at this sampling point generates a READY controlled waitstate,
READY sampled LOW at this sampling point terminates the currently running bus cycle.
5)
If the next following bus cycle is READY controlled, an active READY signal must be disabled before the first
valid sample point for the next bus cycle. This sample point depends on the MTTC waitstate of the current
cycle, and on the MCTC waitstates and the ALE mode of the next following cycle. If the current cycle uses a
multiplexed bus the intrinsic MUX waitstate adds another CLKOUT cycle to the READY deactivation time.
