5.3.6
The acceptance mask register specifies which of the corresponding bits in the acceptance code
register are relevant for acceptance filtering.
Note:
AM0 – AM7 — Acceptance mask bits
When a particular bit in this register is clear this indicates that the corresponding bit in the
acceptance code 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. When a bit is set, it indicates that the state of
the corresponding bit in the acceptance code register will not affect whether or not the message
is accepted.
5.3.7
Note:
SJW1, SJW0 — Synchronization jump width bits
The synchronization jump width defines the maximum number of system clock (t
which a bit may be shortened, or lengthened, to achieve resynchronization on data transitions on
the bus (see
