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

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.

Caution: During normal operation the ICCCLK pin must be pulled- up, internally or externally (external pull-up of 10k mandatory in
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
