Interrupt Pending Register 1 (CAN_IPND1)
These registers contain the IntPnd bits of the 32 Message Objects. By reading the IntPnd bits, the
software can check for which Message Object an interrupt is pending. The IntPnd bit of a specific
Message Object can be set/reset by the application software through the IFn Message Interface
Registers or by the Message Handler after reception or after a successful transmission of a frame.
This will also affect the value of IntId in the Interrupt Register.
