12.8 Port Pin Characteristics
12.8.1 General Characteristics.
Subject to general operating condition for V
Notes:
1. Unless otherwise specified, typical data is based on T
2. Hysteresis voltage between Schmitt trigger switching level. Based on characterization results, not
tested in production.
3. Configuration is not recommended, all unused pins must be kept at a fixed voltage: using the output
mode of the I/O for example or an external pull-up or pull-down resistor (see Figure 12.11. Data based on
design simulation and/or technology characteristics is not tested in production.
