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

supplies, in the permitted range.

2. A positive injection is induced by VIN > VDDIOx while a negative injection is induced by VIN < VSS. IINJ(PIN) must never be

exceeded. Refer also to Table 18: Voltage characteristics for the maximum allowed input voltage values.

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

value.

4. On these I/Os, any current injection disturbs the analog performances of the device.

5. When several inputs are submitted to a current injection, the maximum ∑|IINJ(PIN)| is the absolute sum of the negative

injected currents (instantaneous values).
