24.13.9 MSCAN08 Identifier Acceptance Control Register
IDAM1–IDAM0— Identifier Acceptance Mode
IDHIT1–IDHIT0— Identifier Acceptance Hit Indicator
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.

The CPU sets these flags to define the identifier acceptance filter organization (see
Acceptance

The MSCAN08 sets these flags to indicate an identifier acceptance hit (see
Filter).
