SID10:SID3: Standard Identifier bits
* If OPTREG2.MTYPE = 1, then SID3 is forced to zero.

SID2:SID0: Standard Identifier bits
Standard messages, bits = b’000’
Extended messages, bits = SID2:SID0
Unimplemented: Read as '0’
EXIDE: Extended Identifier Enable bit
1 = Apply filter to RXFnSIDL.EXIDE (filter applies to standard or extended message frames
0 = Do not apply filter to RXFnSIDL.EXIDE (filter will be applied to both standard and extended
