    Please see the TMS320C6455 Data Manual.  It lists the Interrupt Events including the GPIO's interrupt events.  You'll need to use the Event Combiner to output it to a specific interrupt event and this can be masked to drive to a specific interrupt.  The Data Manual references the Megamodule UG and has a link to go over the masking.
