bit 7 bit 0
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 7-5
SID<2:0>: Standard Identifier bits (if EXID = 0)
Extended Identifier bits, EID<20:18> (if EXID =
1).
bit 4
SRR: Substitute Remote Request bit
bit 3
EXID: Extended Identifier bit
1 = Received message is an extended data frame, SID<10:0> are EID<28:18>
0 = Received message is a standard data frame
