SID10:SID3: Standard Identifier bits, if EXIDE = 0 (TXBnSID Register)
Extended Identifier bits EID28:EID21, if EXIDE = 1
SID2:SID0: Standard Identifier bits, if EXIDE = 0
Extended Identifier bits EID20:EID18, if EXIDE = 1
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’
