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. Positive current injection is not possible on these I/Os. A negative injection is induced by V

< V
SS
. I
INJ(PIN)
must never be
exceeded. Refer to Table 12 for maximum allowed input voltage values.
4. A positive injection is induced by V

INJ(PIN)
must never be
exceeded. Refer to Table 12 for the maximum allowed input voltage values.
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).
