msCAN08 Controller (msCAN08)
Programmer’s model of control registers
IDHIT1- IDHIT0— Identifier Acceptance Hit Indicator
The msCAN08 sets these flags to indicate an identifier acceptance hit
(see Identifier acceptance filter on page 356). Table 11 summarizes
the different settings.

The IDHIT indicators are always related to the message in the
foreground buffer. When a message gets copied from the background to
the foreground buffer the indicators are updated as well.
NOTE: The CIDAC register can only be written if the SFTRES bit in the
msCAN08 Module Control Register is set.
