Notes:
1. Directly connecting the RESET and I/O pins to V
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: 4.7kΩ for
RESET, 10kΩ for I/Os). Unused I/O pins must be tied in the same way to V

3. All power (V
4. Negative injection disturbs the analog performance of the device. In particular, it induces leakage currents throughout
the device including the analog inputs. To avoid undesirable effects on the analog functions, care must be taken:
- Analog input pins must have a negative injection less than 0.8 mA (assuming that the impedance of the analog voltage
is lower than the specified limits)
- Pure digital pins must have a negative injection less than 1.6mA. In addition, it is recommended to inject the current as
far as possible from the analog input pins.
5. When several inputs are submitted to a current injection, the maximum ΣI
and negative injected currents (instantaneous values). These results are based on characterisation with ΣI
mum current injection on four I/O port pins of the device.
