1. Data based on design simulation only. Not tested in production.
2. The leakage could be higher than the maximum value, if negative current is injected on adjacent pins. Refer to Table 45:
I/O current injection susceptibility.
3. To sustain a voltage higher than V
DDIOx
+ 0.3 V, the internal pull-up/pull-down resistors must be disabled.
4. Pull-up and pull-down resistors are designed with a true resistance in series with a switchable PMOS/NMOS. This
PMOS/NMOS contribution to the series resistance is minimal (~10% order).
