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
Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared x = Bit is unknown
