13.8 I/O PORT PIN CHARACTERISTICS
13.8.1 General Characteristics
Subject to general operating conditions for V
Notes:
1. Data based on characterization results, not tested in production.
2. 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
based on design simulation and technology characteristics, not tested in production. This value depends on V
perature values.
3. The R

4. 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.

(external pull-up of 10k mandatory in noisy environment. This is to avoid entering ICC mode unexpectedly during a reset.
Caution: During normal operation the ICCCLK pin must be pulled-up, internally or externally
Note: I/O can be left unconnected if it is configured as output (0 or 1) by the software. This has the advantage of greater EMC
robustness and lower cost.
