26.3.10.3. Message Object Interrupts

The IntPnd bits from the message objects can generate interrupts when the corresponding message object TxIE bit or RxIE bit is set to 1. The table lists the location of message object interrupt information in the interrupt pending registers. The interrupt pending registers are located in the message handler group (msghandgrp).
