Bit 30 – MIDE Identifier Receive Mode

ValueDescription
1 Matches only message types (standard or extended address) that correspond to the EXIDE bit of 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))

Bits 28:11 – MEID[17:0] Extended Identifier Mask
