The INT Signal can be used only on a special mode of GPIF called the PP Mode. I hope you are using it in the normal mode. (Refre programmers manual for more details on PP Mode)
I recommend you to use ordinary GPIO Interrupt for your application.

Please explain further the meaning of PP mode!
What do you mean with ordinary GPIO mode? Should we set the IO pin to generate Interrrupts when it changes state??
