3.7.3.1 12-bit DAC Overview
This device contains two 12-bit digital-to-analog converters (DAC) with programmable
reference generator output. The DAC includes a FIFO for DMA support.
3.7.3.2 12-bit DAC Output
The output of the DAC can be placed on an external pin or set as one of the inputs to the
analog comparator or ADC.
