I/O port pin characteristics
General characteristics
Subject to general operating conditions for V
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.
Table 29.
Notes:
1. Data based on characterization results, not tested in production.
2. Hysteresis voltage between Schmitt trigger switching levels. Based on characterization results, not tested.
3. When the current limitation is not possible, the V
4. Leakage could be higher than max. if negative current is injected on adjacent pins.
