Notes:
1. Unless otherwise specified, typical data are based on T
2. Data based on characterization results, not tested in production.
3. Hysteresis voltage between Schmitt trigger switching levels. Based on characterization results, not tested.

5. Data based on characterization results, not tested in production.
6. To generate an external interrupt, a minimum pulse width has to be applied on an I/O port pin configured as an external
interrupt source.
