12.2 ABSOLUTE MAXIMUM RATINGS

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). For the same reason, unused I/O pins must not be directly tied to V
2. I

4. Negative injection disturbs the analog performance of the device. See note in
For best reliability, it is recommended to avoid negative injection of more than 1.6mA.
5. When several inputs are submitted to a current injection, the maximum ΣI

mum current injection on four I/O port pins of the device.
6. True open drain I/O port pins do not accept positive injection.
