Electrical Specifications
21.3 Absolute Maximum Ratings
Maximum ratings are the extreme limits to which the MCU can be
exposed without permanently damaging it.
NOTE:
This device is not guaranteed to operate properly at the maximum
ratings. Refer to 21.6 DC Electrical Characteristics for guaranteed
operating conditions.

NOTE:
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 operation, it is recommended that V_IN and V_OUT be constrained
to the range V_SS ≤ (V_IN or V_OUT) ≤ V_DD. Reliability of operation is
enhanced if unused inputs are connected to an appropriate logic
voltage level (for example, either V_SS or V_DD.)
