    FX3 INT# / CTL15 interrupt example



      Is there an example of how to configure the INT# / CTL15 pin to handle interrupts on the FX3?  Using GPIF II Designer I tried configuring an input signal on the INT pin, then defined a state machine that sends INTR_CPU on an INT trigger.  I do see the pin go low (Polarity -> Active Low) but never see the firmware callback function called.  What else do I need to do?


      In the firmware code:


      AppThread_Entry (
              uint32_t input)




        CyU3PGpifSMStart (START, ALPHA_START);


        // register GPIF callback
