The C0GMRk, C0LMARk and C0LMBRk registers are used for acceptance filtering.
The users can select and receive user-desired messages.
The C0GMRk register determines whether IDs in the message slots 0 to 13 are verified. The
C0LMARk register determines whether ID in the message slot 14 is verified. The C0LMBRk register
determines whether ID in the message slot 15 is verified.
Figure 23.27 shows each mask register and corresponding message slot. Figure 23.28 shows the
acceptance filtering.

1. Change the C0GMRk register setting only when the message slots 0 to 13 have no receive request.
2. Change the C0LMARk register setting only when the message slot 14 has no receive request.
3. Change the C0LMBRk register setting only when the message slot 15 has no receive request.
4. More than two message slots are able to store a receive message ID, the ID is stored into the
