IDHIT2 – IDHIT0 — Identifier Acceptance Hit Indicator
The msCAN12 sets these flags to indicate an identifier acceptance hit
(see Identifier Acceptance Filter). Table 17-8 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.

set.
