For Standard ID
Registers CiGMRk, CiLMARk, and CiLMBRk (i = 0, 1, k = 0 to 4) are used for acceptance filtering.
By using these registers, users are able to select which messages to receive.
The CiGMRk register determines whether IDs in the message slots 0 to 13 are checked or not. The CiLMARk
register determines whether ID in the message slot 14 is checked or not. The CiLMBRk register determines
whether ID in the message slot 15 is checked or not.
NOTES:
Figure 23.28 shows individual mask registers and corresponding message slots. Figure 23.29 shows the
acceptance filtering.

•
1. Change the CiGMRk register while none of the message slots 0 to 13 has a receive request.
2. Change the CiLMARk register while the message slot 14 has no receive request.
3. Change the CiLMBRk register while the message slot 15 has no receive request.
4. When there are two or more receive message slots which have the matched ID with the received message,
When the bit in the CiGMRk, CiLMARk, or CiLMBRk register is set to 0, the corresponding bit (ID bit) in
the CANi message slot j’s (j = 0 to 15) standard ID0, standard ID1, or extended ID0 to extended ID2 is
masked in acceptance filtering. (The corresponding bit is assumed to have a matching ID.)
When the bit in the CiGMRk, CiLMARk, CiLMBRk register is set to 1, the corresponding ID bit is
compared with a received ID in acceptance filtering. When the received ID matches the ID set in the
message slot j, the receive data is stored into the message slot having the matched ID.
the received message is stored into the smallest-numbered message slot.
