(d) CANn module mask 4 register (CnMASK4L, CnMASK4H)
Note:
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.
After reset: Undefined
