The C0GMRj, C0LMARj and C0LMBRj registers are used for acceptance filtering.
The C0GMRj register determines whether the IDs in the message slots 0 to 13 are verified. The
C0LMARj register determines whether the ID in the message slot 14 is verified. The C0LMBRj register
determines whether the ID in the message slot 15 is verified.

1. Change the C0GMRj register only when the message slots 0 to 13 have no receive request.
2. Change the C0LMARj register only when the message slot 14 has no receive request.
