Interrupt Identifier (Indicates the source of the interrupt. Ref. Table 5-18)
If several interrupts are pending, the CAN Interrupt Register will point to the pending
interrupt with the highest priority, disregarding their chronological order. An interrupt
remains pending until the application software has cleared it. If IntId is different from
0x0000 and IE is set, the IRQ interrupt signal to the EIC is active. The interrupt
remains active until IntId is back to value 0x0000 (the cause of the interrupt is reset)
or until IE is reset.
The Status Interrupt has the highest priority. Among the message interrupts, the
Message Object’ s interrupt priority decreases with increasing message number.
A message interrupt is cleared by clearing the Message Object’s IntPnd bit. The Status
Interrupt is cleared by reading the Status Register.
Number of Message Object which caused the interrupt.
