7.0. 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 5V VCC or 4.096V may serve as a voltage reference
source. The result of conversion is transferred from the ADC module to the microcontroller via the Serial Peripheral
Interface (SPI).

In order to enable the ADC module to be turned on, switches 4-7 on the DIP switch SW9 should be set to the ON
position, Figure 7-3. Jumper 11 is used as a voltage reference source selector, Figure 7-4.
