bit 7-5
bit 4
SID<2:0>: Standard Identifier bits (if EXID = 0)
Extended Identifier bits, EID<20:18> (if EXID = 1).
SRR: Substitute Remote Request bit
This bit is always ‘1’ when EXID = 1or equal to the value of RXRTRRO (RBXnCON<3>) when EXID = 0.
EXID: Extended Identifier bit
bit 3
1= Received message is an extended data frame, SID<10:0> are EID<28:18 >
0= Received message is a standard data frame
bit 2
Unimplemented: Read as ‘0’
