2.
Directly connecting the RESET and I/O pins to VDD or VSS could damage the device if an unintentional
internal reset is generated or an unexpected change of the I/O configuration occurs (for example, due to a
corrupted program counter). To guarantee safe operation, this connection has to be done through a pull-up
or pull-down resistor (typical: 4.7 k
Ω for RESET, 10 kΩ for I/Os). For the same reason, unused I/O pins
must not be directly tied to VDD or VSS.

IINJ(PIN)

3.
IINJ(PIN) must never be exceeded. This is implicitly insured if VIN maximum is respected. If VIN maximum
cannot be respected, the injection current must be limited externally to the IINJ(PIN) value. A positive
injection is induced by VIN>VDD while a negative injection is induced by VIN<VSS. For true open-drain pads,
there is no positive injection current, and the corresponding VIN maximum must always be respected.
4.
Negative injection disturbs the analog performance of the device. See note in ADC accuracy on page 145.
For best reliability, it is recommended to avoid negative injection of more than 1.6 mA.

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). These results are based on
characterization with
ΣI
INJ(PIN) maximum current injection on four I/O port pins of the device.
6.
True open drain I/O port pins do not accept positive injection.
