NOTES:

1. The external signal sets the interrupt flag every time the minimum t(int) cycle and time parameters are met. It may be set even with

trigger signals shorter than t(int). Both the cycle and timing specifications must be met to ensure the flag is set. t(int) is measured in

MCLK cycles.

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 an input.
