Note) Absolute Maximum Ratings is values which must not be exceeded to guarantee device reliability and life, and when using a
device in excess even a moment, it may immediately cause damage to device or may significantly deteriorate its reliability
With a system of which a voltage at an input pin might exceed a supply voltage of VDDA/GND, use an external diode to
assure that the voltage does not exceed the absolute maximum rating.
