Could NMI/PTA4 pin be both NMI and GPIO with interrupt? I have tried enabling NMI, which generate
Cpu_OnNMIINT function that I could use to tell NMI is interrupt. For the GPIO, I used BitIO with ExtInt_LDD. When I ran the code, it seem the GPIO interrupt is not triggering. Anyone have any guideline or example to get these working? Currently, I used processor expert to set things up. Thanks for the help.
