SID10 SID9 SID8 SID7 SID6 SID5 SID4 SID3*
bit 7 bit 0
bit 7-0 SID10:SID3: Standard Identifier bits
* If OPTREG2.MTYPE = 1, then SID3 is forced to zero.

bit 3 EXIDE: Extended Identifier Enable bit
1 = Apply filter to RXFnSIDL.EXIDE (filter applies to standard or extended message frames
depending on filter bit)
0 = Do not apply filter to RXFnSIDL.EXIDE (filter will be applied to both standard and extended
message frames)
