12.8 I/O PORT PIN CHARACTERISTICS
12.8.1 General Characteristics
Subject to general operating condition for VDD, fOSC, and TA unless otherwise specified.
Figure 77. Two typical Applications with unused I/O Pin
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 77). 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. This data is based on characterization results,
not tested in production.
6. 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.
