RX23W Group 36. CAN Module (RSCAN)
36.2.19 Receive Rule Entry Register jAH (GAFLIDHj) (j = 0 to 15)
Modify the GAFLIDHj register only when the GRWCR.RPAGE bit is set to 0 in global reset mode.
GAFLID[28:16] Bits (ID Set H)
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.
GAFLLB Bit (Receive Rule Target Message Select)
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.
GAFLRTR Bit (RTR Select)
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.
GAFLIDE Bit (IDE Select)
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.
