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

supply, in the permitted range.

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

specified maximum value.

3. A positive injection is induced by VIN>VDD while a negative injection is induced by VIN <VSS. IINJ(PIN) must

never be exceeded. Refer also to Table 17: Voltage characteristics for the maximum allowed input voltage

values.

4. A positive injection is induced by VIN>VDDA while a negative injection is induced by VIN<VSS. IINJ(PIN) must

never be exceeded. Refer also to Table 17: Voltage characteristics for the maximum allowed input voltage

values. Negative injection disturbs the analog performance of the device. See note 2 below Table 56 on

page 78.

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).
