EID7:EID0: Extended Identifier bits
SID2:SID0: Standard Identifier bits, if EXID = 0
Extended Identifier bits EID20:EID18, if EXID = 1
SRR: Substitute Remote Request bit
This bit is always ‘0’ when EXID = ‘1’, or equal to the value of RXRTRRO (RXnBCON<3>)
when EXID = ‘0’.
EXID: Extended Identifier bit
1 = Received message is an Extended Data Frame, SID10:SID0 are EID28:EID18
0 = Received message is a Standard Data Frame
Unimplemented: Read as ’0’
EID17:EID16: Extended Identifier bits
