21.9 Message Reception
21.9.1 Message reception
modes in order to store newly receive messages.
the priority explained below. The message is always stored in the message buffer with the highest priority, not in a
message buffer with a low priority. For example, when an unmasked receive message buffer and a receive message
buffer linked to mask 1 have the same ID, the received message is not stored in the message buffer linked to mask 1
that has not received a message, even if a message has already been received in the unmasked receive message
buffer. In other words, when a condition has been set to store a message in two or more message buffers with
different priorities, the message buffer with the highest priority always stores the message; the message is not stored
in message buffers with a lower priority. This also applies when the message buffer with the highest priority is unable
to receive and store a message (i.e., when the DN bit = 1 indicating that a message has already been received, but
rewriting is disabled because the OWS bit = 0). In this case, the message is not actually received and stored in the
candidate message buffer with the highest priority, but neither is it stored in a message buffer with a lower priority.

All buffers satisfying the following conditions are searched in all the message buffer areas in all the operation
• Used as a message buffer
• Set as a receive message buffer
• Ready for reception
Remark m = 00 to 31
When two or more message buffers of the CAN module receive a message, the message is stored according to
(C0MCONFm.MA0 bit is set to 1.)
(C0MCONFm.MT2 to C0MCONFm.MT0 bits are set to 001B, 010B, 011B, 100B, or 101B.)
(C0MCTRLm.RDY bit is set to 1.)
