(1) An external signal sets the interrupt flag every time the minimum interrupt pulse width t
(int)
is met. It may be set even with trigger signals
shorter than t

applied to the corresponding pin(s), unless otherwise noted.
(2) The leakage of the digital port pins is measured individually. The port pin is selected for input and the pullup/pulldown resistor is
disabled.
