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), ie. the on-chip CAN-
Module 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 MBaud. The
CAN-Module uses two pins of Port 4 to interface to a bus transceiver.
Note: When the CAN interface is to be used the segment address output on Port 4 must be limited
Parallel Ports
The C164CI provides up to 59 IO lines which are organized into five 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 two IO
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.
All port lines have programmable alternate input or output functions associated with them.
PORT0 may be used as address and data lines when accessing external memory, while Port 4
outputs the additional segment address bits A21/19/17...A16 in systems where segmentation is
enabled to access more than 64 KBytes of memory.
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 3 includes alternate functions of timers, serial interfaces, the optional bus control signal BHE
and the system clock output (CLKOUT).
Port 5 is used for the analog input channels to the A/D converter.
All port lines that are not used for these alternate functions may be used as general purpose IO
lines.
Semiconductor Group
to 4 bits, ie. A19...A16. This is necessary to enable the alternate function of the CAN
interface pins.
