ADC module
The ADC module is used to convert an analog voltage level into the appropriate 12-bit digital value. The analog voltage signal is
supplied via screw terminals CH0, CH1, CH2, and CH3. The ADC module is built-in into the microcontroller. The voltage supplied
from the VREF pin is used as a voltage reference. In order to use this voltage, switch 8 on the DIP SW14 should be set to the ON
position.
