I have observed that P0.4 is an active high IRQ. Is there any way to configure this to be edge sensitive? Any example code to do this?
Thank you, Bob
The interrupts on the ADuC7020 cannot be configured to be edge sensitive.
It should be possible using the PLA to detect edges on the two interrupts that are also PLA inputs: IRQ2 on P1.4 and IRQ3 on P1.5.
