t(int)

External interrupt timing

Port P1, P2: P1.x to P2.x, External

trigger puls width to set interrupt

flag, (see Note 1)

2.2 V/3 V

NOTES:

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

shorter than t(int).

NOTES:

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 pull-up/pull-down resistor is

disabled.
