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 QFP packages.

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

value.

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 12: Voltage characteristics for the maximum allowed input voltage values.

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 12: Voltage characteristics for the maximum allowed input voltage values. Negative injection

disturbs the analog performance of the device. See note (2) below Table 51: ADC accuracy.

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).
