Problem while setting up AMUTEIN0 to generate INT13 on TMS320C6727B (Interrupt routine is not executing)

Hi,

I am unable to execute ISR hooked up to INT13 of C6727. I configured an external pin(SPI0_ENA) as source of AMUTEIN0 and configured dMAX to generate event26 and INT13. My code is given below. Plz suggest me, where is the problem. I get bit 26 of DEFR flag register '1' when interrupt occurs on SPI0 ENA pin but interrupt routine is not executed at all.
