so even though I have the input sitting high, I have to pull it low and then the Int does not fire until I realease the input.
what is "realease the input". An interrupt with the corresponding IT set will set the corresponding IE 1-2 cycles after the transition from high to low if the pulse is 2 cycles or more wide The IE will fire the interrupt in the moment the interrupt is enabled. Erik |
