TMS320F28035: TMS320F28035 interrupt external

Part Number: TMS320F28035


Tool/software:

If I  have more than 3 interrupt external signals that are connected to GPIO pins, how can I manage them?

Maybe I have misanderstood, but it seems that only XINT1, XINT2 and XINT3 are available.

If more than 1 GPIO is related to XINT1, for exmple, Is there some way to distinguish wich GPIO has generated interrupt?

Or should I use the Capture inputs interrutp? I have not yet studied  them.
