AC7 – AC0 — Acceptance Code Bits
The CIDAR0–7 registers can only be written if the SFTRES bit in
CMCR0 is set.
The identifier mask register specifies which of the corresponding bits in
the identifier acceptance register are relevant for acceptance filtering. To
receive standard identifiers in 32 bit filter mode it is required to program
the last three bits (AM2–AM0) in the mask registers CIDMR1 and

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.
