RX23W Group 36. CAN Module (RSCAN)
36.2.43 Receive FIFO Access Register mDL (RFDF2m) (m = 0, 1)
When the RFPTRm.RFDLC[3:0] value is smaller than 1000b, data bytes for which no data is set are read as 00h.
This register can be read when the GRWCR.RPAGE bit is 1.
36.2.44 Receive FIFO Access Register mDH (RFDF3m) (m = 0, 1)
When the RFPTRm.RFDLC[3:0] value is smaller than 1000b, data bytes for which no data is set are read as 00h.
This register can be read when the GRWCR.RPAGE bit is 1.
