MVOL [3: 0] (W); Master VOLume

Indicates the output master volume to the D / A converter.
This is to control the overall output level. Clipping noise does not disappear even if the gain is lowered by lowering the "MVOL" setting value for the output overflow (To eliminate clipping noise) Please reset "DISDL" and "EFSDL" to eliminate the overflow).

DAC18B (W); DAC out 18Bit

Set this bit to “1B” when the digital output is used as an interface of an 18-bit D / A converter. For 16 bits, set "0B". (Basically, a 16-bit type D / A converter is connected, so set "0B" in the register.)
