MSCAN
IDHIT2–IDHIT0 — Identifier Acceptance Hit Indicator
The MSCAN sets these flags to indicate an identifier acceptance hit
(see Identifier Acceptance Filter). Table 92 summarizes the different
settings.
The IDHITx indicators are always related to the message in the
foreground buffer (RxFG). When a message gets shifted into the
foreground buffer of the receiver FIFO the indicators are updated as
well.
Reserved Registers These registers are reserved for factory testing of the MSCAN module
and are not available in normal modes.
