  1. The individual bytes in this multibyte register can be accessed with the following register names:
    • CxMASKyT: Accesses the top byte MASKy[31:24].
    • CxMASKyU: Accesses the upper byte MASKy[23:16].
    • CxMASKy: Accesses the byte MASKy[31:0].
  2. Each Mask is associated with a filter.
  3. [x] denotes Filter number, from 0 to 15.

Bit 30 – MIDE Identifier Receive Mode bit

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)).

Bit 29 – MSID11 12th bit of Standard Identifier Mask bit

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

In DeviceNet mode, these are the mask bits for the first two data bytes.

Bits 10:0 – MSID[10:0] Standard Identifier Mask bits
