AM7–AM0 — Acceptance Mask Bits
If a particular bit in this register is cleared this indicates that the
corresponding bit in the identifier acceptance register must be the
same as its identifier bit, before a match will be detected. The
message will be accepted if all such bits match. If a bit is set, it
indicates that the state of the corresponding bit in the identifier
acceptance register will not affect whether or not the message is
accepted.
Bit description:
1 = Ignore corresponding acceptance code register bit.
0 = Match corresponding acceptance code register and identifier
bits.
NOTE: The CIDMR0-3 registers can only be written if the SFTRES bit in the
msCAN08 Module Control Register is set
