13.8 I/O PORT PIN CHARACTERISTICS
13.8.1 General Characteristics
Subject to general operating conditions for VDD, fOSC, and TA unless otherwise specified.
.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. Configuration 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 ). Data based on design simulation and/or technology
characteristics, not tested in production.
5. The RPU pull-up equivalent resistor is based on a resistive transistor (corresponding IPU current characteristics de-
scribed in Figure 89). This data is based on characterization results, tested in production at VDD=5V.
6. Data based on characterization results, not tested in production.
7. 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.
