SID10 SID9 SID8 SID7 SID6 SID5 SID4 SID3
bit 7 bit 0
bit 7-0 SID10:SID3: Standard Identifier bits, if EXID = 0 (RXBnSIDL<3>);
Extended Identifier bits EID28:EID21, if EXID = 1.
Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
- n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown

bit 7 bit 0
bit 7-5 SID2:SID0: Standard Identifier bits, if EXID = 0;
Extended Identifier bits EID20:EID18, if EXID = 1.
bit 4 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.
bit 3 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
bit 2 Unimplemented: Read as ‘0’
bit 1-0 EID17:EID16: Extended Identifier bits
Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
- n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
