MOIPA

Interrupt pending bits for Message Objects 1 to 32. By reading the IntPnd bits, the CPU can check for which Message Object an interrupt is pending. The IntPnd bit of a specific Message Object can be set/reset by the CPU via the IFx Message Interface Registers or set by the Message Handler after reception or after a successful transmission of a frame. This will also affect the valid of IntID in the Interrupt Register.
