2. Data based on characterization results, not tested in production.
3. Hysteresis voltage between Schmitt trigger switching levels. Based on characterization results, not tested.
4. The R pull-up equivalent resistor is based on a resistive transistor. This data is based on characterization results,

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.
