1. All main power (VDD, VDDA) and ground (VSS and 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.The total output current must not be
sunk/sourced between two consecutive power supply pins referring to high pin count LQFP packages
3. Positive injection is not possible on these I/Os and does not occur for input voltages lower than the specified maximum
value.
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 19: Voltage characteristics for the maximum allowed input voltage values.
5. 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 19: Voltage characteristics for the maximum allowed input voltage values. Negative injection
disturbs the analog performance of the device. See note (2) below Table 68.
6. 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).
