4. I
INJ(PIN)
must never be exceeded. This is implicitly insured if V
IN
maximum is respected. If V
IN
maximum
cannot be respected, the injection current must be limited externally to the I
INJ(PIN)
value. A positive
injection is induced by V
IN
>V
DD
while a negative injection is induced by V
IN
<V
SS
. For true open-drain pads,
there is no positive injection current, and the corresponding V
IN
maximum must always be respected
5. Negative injection disturbs the analog performance of the device. See note in Section 10.3.10: 10-bit ADC
characteristics on page 82.
Injected current on NRST pin ±4
Injected current on OSCIN pin ±4
Injected current on any other pin

6. 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). These results are based on
characterization with ΣI
INJ(PIN)
maximum current injection on four I/O port pins of the device.
