Alternate Mute. Setting this bit mutes the ALT_LINE_OUT_L/R output signals.
Alternate Volume Left. These bits control the left alternate output volume. Each step corre-
Alternate Volume Left Max Attenuation. Setting ML5 sets the left channel attenuation to

Alternate Volume Right Max Attenuation. Setting MR5 sets the right channel attenuation to
8000h. This value corresponds to 0 dB attenuation and Mute ‘set’.
Mono Mute. Setting this bit mutes the MONO_OUT signal.
Mono Volume. These bits control the mono output volume. Each step corresponds to 1.5 dB
gain adjustment, with a total available range from 0 dB to -46.5 dB attenuation. See Table 2 for
further attenuation levels.
Mono Volume Max Attenuation. Setting the MM5 bit sets the mono attenuation to -46.5 dB by
forcing MM[4:0] to a ‘1’ state. MM[5:0] will read back 011111 when MM5 has been ‘set’. Table 2
summarizes this behavior.
8000h. This value corresponds to 0 dB attenuation and Mute ‘set’.
