! ! ! ! Explanation for external components
(1) AD input pin (example when used as a temperature sensor)
To the AD input pin, input a voltage with divided resistance from a resistor and NTC thermistor. For the sensor to
measure the temperature, the NTC thermistor is used. The thermistor is a p-type semiconductor and as the temperature
increases, the resistance value becomes lower. In other words, the resistance temperature coefficient is negative,
and so the AD input pin voltage temperature characteristics are also negative.
