NOTES:

1. The external signal sets the interrupt flag every time the minimum t(int) parameters are 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 port pin must be selected as input.
