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. Negative injection disturbs the analog performance of the device. See note in Section 5.3.20: 12-bit ADC
characteristics.
3. Positive injection is not possible on these I/Os. A negative injection is induced by VIN<VSS. IINJ(PIN) must
never be exceeded. Refer to Table 9 for the values of the maximum allowed input voltage.
4. A positive injection is induced by VIN>VDD while a negative injection is induced by VIN<VSS. IINJ(PIN) must
never be exceeded. Refer to Table 9 for the values of the maximum allowed input voltage.
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).
