(1)
The leakage current is measured with V

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 or pulldown resistor is
disabled.
(3)
An external signal sets the interrupt flag every time the minimum interrupt pulse duration t
(int)
is met. It may be set by trigger signals
shorter than t
(int)
.
