TMS320F28035: Using GPIO's as External Interrupts

Part Number: TMS320F28035

Hello,

I am using the TMS320F28035 to read three hall signals from a motor.  I am wanting to use external interrupts for each hall signal.  However, I am a bit confused about the interrupt control registers.  In the data sheet, the TMS320F28035 shows to have external interrupts labeled as "XINT1, XINT2, and XINT3."  But when I referenced TI's "TMS320x280x, 2801x, 2804x DSP System Control and Interrupts Reference Guide," The external interrupts are listed as "XINT1, XINT2, and XNMI."  Also, the System and Control reference guide did not mention anything about XINT3.  I am confused on how to use a third external interrupt and what the control and select registers would be for the XINT3 or XNMI interrupts.  I am using the 80 pin device, if that helps.  Can someone please help me to clear up this confusion?  Thank you very much.
