      9description: |
     10  The STM32 DAC is a 12-bit voltage output digital-to-analog converter. The DAC
     11  may be configured in 8 or 12-bit mode. It has two output channels, each with
     12  its own converter.
     13  It has built-in noise and triangle waveform generator and supports external
     14  triggers for conversions. The DAC's output buffer allows a high drive output
     15  current.
