11.9 Port Pin Characteristics

11.9.1 General Characteristics.

Subject to general operating condition for VDD,fosc, and TA, unless otherwise specified.

Notes:

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

2. Hysteresis voltage between Schmitt trigger switching level. Based on characterization results, not

tested in production.
