15.8 I/O PORT PIN CHARACTERISTICS
15.8.1 General Characteristics
Subject to general operating conditions for V
Figure 81. Two typical Applications with unused I/O Pin
Figure 82. Typical I
Notes:
1. Unless otherwise specified, typical data is based on T
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
characteristics, not tested in production.
5. The R
scribed in
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.
