I/O pin capacitance

1. Guaranteed by test in production

2. Hysteresis voltage between Schmitt trigger switching levels. Guaranteed by characterization results.

3. With a minimum of 200 mV. Guaranteed by characterization results.

4. The max. value may be exceeded if negative current is injected on adjacent pins.

5. Pull-up and pull-down resistors are designed with a true resistance in series with a switchable PMOS/NMOS.
