1. All main power (V
DD
, V
DDA
) and ground (V
SS
, 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. Negative injection disturbs the analog performance of the device. See note in Section 6.3.20: 12-bit ADC characteristics.
4. Positive injection is not possible on these I/Os and does not occur for input voltages lower than the specified maximum
value.
5. When several inputs are submitted to a current injection, the maximum
ΣI
INJ(PIN)
is the absolute sum of the positive and
negative injected currents (instantaneous values).
