RMVA [4:0]
RMVA [4:0] Right Master Volume Attenuation. The LSB represents –1.5 dB, 00000 = 0 dB and the range is 0 dB to
–46.5 dB. This register is added with the Hardware Volume Button Modifier value to produce the final DAC Master
Volume attenuation level. See Hardware Volume Button Modifier Register description for more details.
RMVM
Right Master Volume Mute. 0 = Unmuted, 1 = Muted.
LMVA [4:0] Left Master Volume Attenuation. The LSB represents –1.5 dB, 00000 = 0 dB and the range is 0 dB to
–46.5 dB. This register is added with the Hardware Volume Button Modifier value to produce the final DAC Master
Volume attenuation level. See Hardware Volume Button Modifier Register description for more details.
