19. CAN Module
The CAN (Controller Area Network) module for the M16C/6N Group (M16C/6N4) of MCUs is a communication
controller implementing the CAN 2.0B protocol. The M16C/6N Group (M16C/6N4) contains two CAN modules
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.

This controller handles the bus arbitration and the CAN protocol services, i.e. bit

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 CiGMR register (i = 0, 1), the CiLMAR register, or the CiLMBR
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.
