Modify this register only when the CFCCH0.CFM[1:0] value is 01b (transmit mode). This register is readable only when
the CFCCH0.CFM[1:0] value is 00b (receive mode).
This register can be read/written when the GRWCR.RPAGE bit is 1.
CFID[15:0] Bits (Transmit/Receive FIFO Buffer ID Data L)
These bits indicate the ID of the received message stored in the transmit/receive FIFO buffer when the
