26.3.1.1.4. Interrupt Pending (IntPnd)

  • 0= This message object is not the source of an interrupt.
  • 1= This message object is the source of an interrupt. The interrupt identifier field in the CAN interrupt register (CIR) points to this message object if there is no other interrupt source with higher priority.

The IntPnd field is directly readable from the interrupt pending registers (MOIPA, MOIPB, MOIPC, MOIPD, and MOIPX). However, to write to the IntPnd field for a specific message object, the host processor must write to the message interface registers.
