to set interrupt flag

(1)

Some devices may contain additional ports with interrupts. See the block diagram and terminal function descriptions.

(2)

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).

Leakage Current – General Purpose I/O

(1)

The leakage current is measured with VSS or VCC 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.
