13.0. 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 CN15 and CN16. 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 switch
SW14 should be set to the ON position.

Figure 13-2: Jumper J9
If the voltage, necessary to perform A/D conversion, is not supplied from an external source, then the 3.3V power
supply voltage is used. In this case, it is necessary to place jumper J9 on the appropriate pins, Figure 13-2.
