6.1.21 Extended Audio DAC1/ADC1 Rate (Index 40h)
SR[15:0]
Extended Audio DAC1/ADC1 Sample Rate.
Default
Read-only value BB80h, indicating 48 kHz sample rate.
6.1.22 Extended Audio DAC2/ADC2 (Index 44h)
SR[15:0]
Extended Audio DAC2/ADC2 Sample Rate.
Default
Read-only value BB80h, indicating 48 kHz sample rate.
6.1.23 Extended Audio DAC1/ADC1 Level (Index 46h)
Mute[D15] Mute. Mutes the input of Extended Audio DAC1.
Mute[D7]
Mute. Mutes the output of Extended Audio ADC1.
DAC[3:0]
Extended Audio DAC1 attenuation. Least significant bit represents 1.5 dB with 00000 = 0 dB. The total
range is 0 dB to -22.5 dB.
ADC[3:2]
Extended Audio ADC1 gain. Least significant bit represents 6 dB with 00 = 0 dB. The total range is 0 dB
to +18 dB.
Default
8080h indicating mute with 0 dB attenuation or gain.
When EAM of the AC Mode Control (Index 5Eh) is set, the Extended Audio DAC1 attenuation is
controlled by ML[4:0] of the Alternate Volume (Index 04h) register.
6.1.24 Extended AudioDAC2/ADC2 Level (Index 4Ah)
Mute[D15] Mute. Mutes the input of Extended Audio DAC2.
Mute[D7]
Mute. Mutes the output of Extended Audio ADC2.
DAC[3:0]
Extended Audio DAC2 attenuation. Least significant bit represents 1.5 dB with 00000 = 0 dB. The total
range is 0 dB to -22 dB.
ADC[3:2]
Extended Audio ADC2 gain. Least significant bit represents 6 dB with 00 = 0 dB. The total range is 0 dB
to +18 dB.
Default
8080h indicating mute with 0 dB attenuation or gain.
When EAM of the AC Mode Control (Index 5Eh) is set, the Extended Audio DAC2 attenuation is
controlled by MR[4:0] of the Alternate Volume (Index 04h) register.
