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:
CyU3PGpifSMStart (START, ALPHA_START);
// register GPIF callback
