1. All main power (V
DD
, V
DDA
) and ground (V
SS
and V
SSA
) 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 V

disturbs the analog performance of the device. See note

below Table 68.
6. When several inputs are submitted to a current injection, the maximum I
INJ(PIN)
is the absolute sum of the positive and
negative injected currents (instantaneous values).
