36.2.37
Receive FIFO Access Register mAL (RFIDLm) (m = 0, 1)
This register can be read when the GRWCR.RPAGE bit is 1.
RFID[15:0] Bits (Receive FIFO Buffer ID Data L)
These bits indicate the ID of the message stored in the receive FIFO buffer.
36.2.38
Receive FIFO Access Register mAH (RFIDHm) (m = 0, 1)
This register can be read when the GRWCR.RPAGE bit is 1.
RFID[28:16] Bits (Receive FIFO Buffer ID Data H)
These bits indicate the ID of the message stored in the receive FIFO buffer.
RFRTR Bit (Receive FIFO Buffer RTR)
This bit indicates the frame format (data frame or remote frame) of the message stored in the receive FIFO buffer.
RFIDE Bit (Receive FIFO Buffer IDE)
This bit indicates the ID format (standard ID or extended ID) of the message stored in the receive FIFO buffer.
