12.8 I/O PORT PIN CHARACTERISTICS
12.8.1 General Characteristics
Subject to general operating conditions for VDD, fOSC, and TA unless otherwise specified.
Figure 77. Connecting Unused I/O Pins
Figure 78. Typical IPU vs. VDD with VIN=VSS
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 VIN maximum must be respected, otherwise refer to IINJ(PIN) specifica-
tion. A positive injection is induced by VIN>VDD while a negative injection is induced by VIN<VSS. Refer to Section 12.2.2
on page 114 for more details.
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 (corresponding IPU current characteristics de-
scribed in Figure 78).
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.
