Where x = 1 or 2, corresponding to the DAC output VOUTL (x = 1) or VOUTR (x = 2).
Default value: 0
The DAC operation controls are used to enable and disable the DAC outputs, VOUTL and VOUTR. When DACx = 0, the corresponding output generates the audio waveform dictated by the data present on the DATA pin. When DACx = 1, the corresponding output is set to the bipolar zero level, or 0.5 VCC.
