bit 7
bit 0
bit 7-0
SID10:SID3: Standard Identifier bits, if EXIDE (TXBnSIDL<3>) = 0;
Extended Identifier bits EID28:EID21, if EXIDE = 1.
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

Unimplemented: Read as ‘0’
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
Unimplemented: Read as ‘0’
