Notes:
1. Connecting RESET and I/O Pins directly to VDD or VSS could damage the device if the unintentional internal reset is generated
or an unexpected change of I/O configuration occurs (for example, due to the corrupted program counter). In order to guarantee
safe operation, this connection has to be performed via a pull-up or pull-down resistor (typical: 4.7k Ω for RESET, 10K Ω for I/Os).
Unused I/O pins must be tied in the same manner to VDD or VSS according to their reset configuration.
2. When the current limitation is not possible, the VIN absolute maximum rating must be respected, otherwise refer to I INJ(PIN)
specification. A positive injection is induced by VIN>VDD while a negative injection is induced by VIN<VSSto I INJ(PIN) specification.
A positive injection is VIN>VDD while a negative injection is induced by VIN<VSS.
3. All power (VDD) and ground (VSS) lines must always be connected to the external supply.
4. 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).
