bit 7 bit 0
bit 15-13 Unimplemented: Read as ‘0’
bit 12-2 SID<10:0>: Standard Identifier Mask bits
1 = Include bit in the filter comparison
0 = Don’t include bit in the filter comparison
bit 1 Unimplemented: Read as ‘0’
bit 0 MIDE: Identifier Mode Selection bit
1 = Match only message types (standard or extended address) as determined by EXIDE bit in filter
0 = Match either standard or extended address message if the filters match
