NOTE:
AM7–AM0 — Acceptance Mask Bits
The CIDMR0–CIDMR7 registers can be written only if the SFTRES bit in CMCR0
is set.
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.
