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
= SIDx bit 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 EXIDE bit in the filter
0
= Matches either standard or extended address message if filters match (i.e., if (Filter SID) = (Message
SID) or if (Filter SID/EID) = (Message SID/EID))
