AC7 – AC0 — Acceptance Code Bits
AC7 – AC0 comprise a user defined sequence of bits with which the
corresponding bits of the related identifier register (IDRn) of the
receive message buffer are compared. The result of this comparison
is then masked with the corresponding identifier mask register.
NOTE: The CIDAR0–7 registers can only be written if the SFTRES bit in
CMCR0 is set.
