17.2 Introduction
The DAC_8B5V module is a digital to analog converter. The converter works with a resolution of 8 bit
and generates an output voltage between VRL and VRH.
The module consists of configuration registers and two analog functional units, a DAC resistor network
and an operational amplifier.
