(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_(int) .

(1) The leakage current is measured with V_SS or V_CC applied to the corresponding pins, 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.
