Electrical Specifications
18.3 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 18.6 DC Electrical Characteristics for guaranteed
operating conditions.

NOTES:
1. Voltages referenced to V_SS
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_REG. Reliability of operation is enhanced
if unused inputs are connected to an appropriate logic voltage level (for
example, either V_SS or V_REG).
