Datasheet

The CANMSG1INT and CANMSG2INT registers hold the INTPND bits of the 32 message objects.

By reading these bits, the CPU can check which message object has an interrupt pending. The

INTPND bit of a specific message object can be changed through two sources: (1) the CPU via the

CANIFnMCTL register, or (2) the message handler state machine after the reception or transmission

of a frame.

This field is also encoded in the CANINT register.

The CANMSG1INT register contains the INTPND bits of the first 16 message objects in the message

RAM; the CANMSG2INT register contains the INTPND bits of the second 16 message objects.

Software should not rely on the value of a reserved bit. To provide

compatibility with future products, the value of a reserved bit should be

preserved across a read-modify-write operation.
