Maximum ratings are the extreme limits to which the MCU can be
exposed without permanently damaging it.
This device is not guaranteed to operate properly at the maximum
ratings. Refer to

This device contains circuitry to protect the inputs against damage due
to high static voltages or electric fields; however, it is advised that normal
precautions be taken to avoid application of any voltage higher than
maximum-rated voltages to this high-impedance circuit. For proper
