Mask pattern setting of ID bit
The ID bits of the message buffer set by the CMID28 to CMID0 bits are compared with the
ID bits of the received message frame.
The ID bits of the message buffer set by the CMID28 to CMID0 bits are not compared with
the ID bits of the received message frame (they are masked).

(c) CANn module mask 3 register (CnMASK3L, CnMASK3H)
(d) CANn module mask 4 register (CnMASK4L, CnMASK4H)
Masking is always defined by an ID length of 29 bits. If a mask is assigned to a
message with a standard ID, the CMID17 to CMID0 bits are ignored.
Therefore, only the CMID28 to CMID18 bits of the received ID are masked.
The same mask can be used for both the standard and extended IDs.
