4.1
Reset Register (Index 00h)
SE[4:0]
Crystal 3D Stereo Enhancement. SE[4:0] = 00110, indicating this feature is present.
ID8
18-bit ADC Resolution. The ID8 bit is ‘set’, indicating this feature is present.
ID7
20-bit DAC resolution. The ID7 bit is ‘set’, indicating this feature is present.
ID4
Headphone Output (Alt Line Out). The ID4 bit is ‘set’, indicating this feature is present.
Default
1990h. The data in this register is read-only data.
Any write to this register causes a Register Reset to the default state of the audio (Index 00h - 38h) and vendor spe-
cific (Index 5Ah - 7Ah) registers. A read from this register returns configuration information about the CS4299.
4.2
Master Volume Register (Index 02h)
Mute
Master Mute. Setting this bit mutes the LINE_OUT_L/R output signals.
ML[5:0]
Master Volume Left. These bits control the left master output volume. Each step corresponds
to 1.5 dB gain adjustment, with 00000 = 0 dB. The total range is 0 dB to -94.5 dB attenuation.
MR[5:0]
Master Volume Right. These bits control the right master output volume. Each step corresponds
to 1.5 dB gain adjustment, with 00000 = 0 dB. The total range is 0 dB to -94.5 dB attenuation.
Default
8000h. This value corresponds to 0 dB attenuation and Mute ‘set’.
