Memory Map and Register Definition
13.3.13 MSCAN Identifier Acceptance Control Register (CAN_IDAC)
The CAN_IDAC register is used for identifier acceptance control.
Read: Anytime
Write: Anytime in initialization mode (INITRQ=1 and INITAK=1), except bits IDHITx,
which are read-only
Address: CAN_IDAC – F440h base + Bh offset = F44Bh

Identifier Acceptance Hit Indicator
The MSCAN sets these flags to indicate an identifier acceptance hit. The IDHITx indicators are always
related to the message in the foreground buffer (CAN_RXFG). When a message gets shifted into the
foreground buffer of the receiver FIFO the indicators are updated as well.
