bit 7 bit 0
bit 7-0 SID10:SID3: Standard Identifier bits if EXIDE = 0 (TXBnSID Register) or
Extended Identifier bits EID28:EID21 if EXIDE = 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 EXIDE = 0 or
Extended Identifier bits EID20:EID18 if EXIDE = 1
bit 4 Unimplemented: Read as ‘0’
bit 3 EXIDE: Extended Identifier enable bit
1 = Message will transmit extended ID, SID10:SID0 becomes EID28:EID18
0 = Message will transmit standard ID, EID17:EID0 are ignored
