The CAN (Controller Area Network) module for the M16C/29 Group of MCUs is a communication controller
implementing the CAN 2.0B protocol. The M16C/29 Group contains one CAN module which can transmit
and receive messages in both standard (11-bit) ID and extended (29-bit) ID formats.
Figure 17.1 shows a block diagram of the CAN module.
External CAN bus driver and receiver are required.

This memory block consists of 16 slots that can be configured either as transmitter
or receiver. Each slot contains an individual ID, data length code, a data field
(8 bytes) and a time stamp.
This block performs filtering operation for received messages. For the filtering
operation, the C0GMR register, the C0LMAR register, or the C0LMBR register is
used.
