Notes:

1. Unless otherwise specified, typical data are based on TA=25°C and VDD=5V.

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 RPU pull-up equivalent resistor is based on a resistive transistor. This data is based on characterization results,

not tested in production.

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.
