pulse width to set interrupt flag(1)
(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) .

nA
(1)
The leakage current is measured with VSS or VCC 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.
