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 V_SS or V_CC applied to the corresponding pin(s), unless otherwise noted.
2. The port pin must be selected as input.
