1. All main power (VDD, VDDA, VDDIO2, VDDUSB, VLCD, VBAT) and ground (VSS, VSSA) pins must always be connected to the

external power supply, in the permitted range.

2. VIN maximum must always be respected. Refer to Table 20: Current characteristics for the maximum allowed injected

current values.

3. This formula has to be applied only on the power supplies related to the IO structure described in the pin definition table.

4. To sustain a voltage higher than 4 V the internal pull-up/pull-down resistors must be disabled.

5. Include VREF- pin.
