received
R/W
12 to 0 GAFLID[28:16] ID Set H Set the ID of the receive rule.
For the standard ID, set these bits to 0.
R/W
Modify the GAFLIDHj register only when the RPAGE bit in the GRWCR register is set to 0 in global reset mode.
• GAFLIDE Bit
This bit is used to select the ID format (standard ID or extended ID) of the receive rule. This bit is compared with
the IDE bit in the received message during the acceptance filter processing.
• GAFLRTR Bit
This bit is used to select the frame format (data frame or remote frame) of the receive rule. This bit is compared
with the RTR bit in the received message during the acceptance filter processing.
• GAFLLB Bit
When this bit is set to 0, data processing using the receive rule is performed when receiving messages
transmitted from another CAN node.
When this bit is set to 1 when the mirror function is used, data processing using the receive rule is performed
when receiving messages transmitted from the own CAN node.
• GAFLID[28:16] Bits
These bits are used to set the ID field of the receive rule. The ID value set by these bits is compared with the ID
in the received message during the acceptance filter processing.
