1. All main power (VDD, VDDA, VDDUSB) and ground (VSS, VSSA) pins must always be connected to the external power supply,

in the permitted range.

2. This current consumption must be correctly distributed over all I/Os and control pins.

3. Negative injection disturbs the analog performance of the device. See note in Section 6.3.20: 12-bit ADC characteristics.

4. Positive injection is not possible on these I/Os and does not occur for input voltages lower than the specified maximum

value.

5. When several inputs are submitted to a current injection, the maximum

ΣIINJ(PIN) is the absolute sum of the positive and

negative injected currents (instantaneous values).
