bit 7 bit 0
Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 15-5 SID<10:0>: Standard Identifier bits
1 = Includes bit, SIDx, in filter comparison
0 = Bit, SIDx, is a don’t care in filter comparison
bit 4 Unimplemented: Read as ‘0’
bit 3 MIDE: Identifier Receive Mode bit
1 = Matches only message types (standard or extended address) that correspond to the EXIDE bit in
the filter
0 = Matches either standard or extended address message if filters match
(i.e., if (Filter SIDx) = (Message SIDx) or if (Filter SIDx/EIDx) = (Message SIDx/EIDx))
bit 2 Unimplemented: Read as ‘0’
bit 1-0 EID<17:16>: Extended Identifier bits
1 = Includes bit, EIDx, in filter comparison
0 = Bit, EIDx, is a don’t care in filter comparison
