AC7–AC0 — Acceptance Code Bits
12.13.13 MSCAN08 Identifier Mask Registers (CIDMR0–CIDMR3)
The identifier mask registers specify which of the corresponding bits in the identifier acceptance register
are relevant for acceptance filtering. For standard identifiers it is required to program the last three bits
(AM2–AM0) in the mask register CIDMR1 to ‘don’t care’.
AM7–AM0 — Acceptance Mask Bits
Freescale Semiconductor
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.
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.
1 = Ignore corresponding acceptance code register bit.
0 = Match corresponding acceptance code register and identifier bits.
CIDMRO Address: $0514
CIDMR1 Address: $0515
CIDMR2 Address: $0516
CIDMR3 Address: $0517
The CIDAR0–CIDAR3 registers can be written only if the SFTRES bit in
CMCR0 is set
The CIDMR0–CIDMR3 registers can be written only if the SFTRES bit in
the CMCR0 is set
