SID10:SID3: Standard Identifier Filter bits if EXIDEN = 0 or
Extended Identifier Filter bits EID28:EID21 if EXIDEN = 1
SID2:SID0: Standard Identifier Filter bits if EXIDEN = 0 or
Extended Identifier Filter bits EID20:EID18 if EXIDEN = 1
Unimplemented: Read as ‘0’
EXIDEN: Extended Identifier Filter Enable bit
1 = Filter will only accept extended ID messages
0 = Filter will only accept standard ID messages
Unimplemented: Read as ‘0’
