On the ADuC7023, at what voltage on the input pin will a) a rising edge external interrupt be triggered b) a falling edge external interrupt?
The same question applies for the ADuC7121, ADuC7122, ADuC7124 and ADuC7126.
The external interrupt is added to the GPIO pins, so the threshold voltage is limited by the GPIO. i.e VINL-input Low voltage:
0.8v, VINH-input high voltage 2.0v.
So for a rising edge interrupt, the threshold is 2.0V; for a falling edge interrupt it is 0.8V
