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 (RBXnCON<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
