5.9 Inputs (Ports P1 and P2)over recommended ranges of supply voltage and operating free-air temperature (unless otherwise noted)
||External interrupt timing
||Port P1, P2: P1.x to P2.x, External trigger pulse duration to set interrupt flag(1)
||2.2 V, 3 V
(1) An external signal sets the interrupt flag every time the minimum interrupt pulse duration t(int) is met. It may be set even with trigger signals shorter than t(int).
