19. CAN Module
The CAN (Controller Area Network) module for the M16C/6N Group (M16C/6N5) of MCUs is a communication
controller implementing the CAN 2.0B protocol. The M16C/6N Group (M16C/6N5) contains one CAN module
which can transmit and receive messages in both standard (11-bit) ID and extended (29-bit) ID formats.
Figure 19.1 shows the CAN Module Block Diagram.
External CAN bus driver and receiver are required.

Protocol
This memory block consists of 16 slots that can be configured either as transmitter
CAN I/O pins.
This controller handles the bus arbitration and the CAN protocol services, i.e. bit
timing, stuffing, error status etc.
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.
Used for the time stamp function. When the received message is stored in the
message memory, the timer value is stored as a time stamp.
CAN0 wake-up interrupt request is generated by a message from the CAN bus.
reception interrupt, CAN0 successful transmission interrupt, CAN0 error interrupt,
and CAN0 wake-up interrupt.
