SRS 3D Stereo Enhancement. SE[4:0] = 01001, indicating this feature is present.
18-bit ADC Resolution. The ID8 bit is ‘set’, indicating this feature is present.
20-bit DAC resolution. The ID7 bit is ‘set’, indicating this feature is present.
Loudness. The ID5 bit is ‘set’, indicating this feature is present.
Simulated Stereo. The ID3 bit is ‘set’, indicating this feature is present.
Bass & Treble. The ID2 bit is ‘set’, indicating this feature is present.
Dedicated Mic PCM in Channel. The ID0 bit is ‘set’, indicating this feature is present.
25ADh. The data in this register is read-only data.
Master Mute. Setting this bit mutes the LINE_OUT_L/R output signals.
Master Volume Left. These bits control the left master output volume. Each step corresponds
to 1.5 dB gain adjustment, with a total available range from 0 dB to -46.5 dB attenuation. Set-
ting the ML5 bit sets the left channel attenuation to -46.5 dB by forcing ML[4:0] to a ‘1’ state.
ML[5:0] will read back 011111 when ML5 has been ‘set’. See Table 4 for further details.
Master Volume Right. These bits control the right master output volume. Each step corre-
sponds to 1.5 dB gain adjustment, with a total available range from 0 dB to -46.5 dB attenu-
ation. Setting the MR5 bit sets the right channel attenuation to -46.5 dB by forcing MR[4:0] to
a ‘1’ state. MR[5:0] will read back 011111 when MR5 has been ‘set’. See Table 4 for further
details.
8000h. This value corresponds to 0 dB attenuation and Mute ‘set’.
