I am trying to measure the width of an input signal pulse. I have connected the external signal to the IRQ0 pin.
Using Timer0 on the ADuC7060, I have enabled the Timer Capture function to capture a rising edge on IRQ0.
When I capture rising edge interrupts on IRQ0, it works fine but, when I configure the IRQ0 for falling edges, the Timer capture function doesn't work.
What am I doing wrong?
I have seen a similar issue on the ADuC7020 using the timer capture function on Timer1.
