14.0. DAC module
A DAC module is used to convert 12-bit digital values into appropriate analog voltage values. The analog voltage signal
is delivered via screw terminals CN13 and CN14. The DAC module is built into the microcontroller. The voltage supplied
from the VREF pin on the microcontroller is used as a voltage reference. To enable the use of this voltage, switch 7 on
the DIP switch SW14 should be set to the ON position.
