with a standard ID, CMID17 to CMID0 are ignored. Therefore, only CMID28 to CMID18
of the received ID are masked. The same mask can be used for both the standard and
extended IDs.

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).
