These registers are used to set the master volume for OUTL and OUTR and the gain for mixer output to the OUTL

and OUTR pins. The correspondence between bits and gain settings is shown below. Gain can be set in a range

from 0 dB to –46.5 dB, in 1.5 dB steps. The default value is 60h (gain: 0 dB, mute: ON).

• OMLM:

OUTL output mute control bit

• OMRM:

OUTR output mute control bit

• OMLV[4:0]: OUTL output gain control bits

• OMRV[4:0]: OUTR output gain control bits
