ADC right sample generator select
0 = SR0 Selected (32h)
1 = SR1 Selected (2Ch).
DAC right sample generator select
0 = SR0 Selected (32h)
1 = SR1 Selected (2Ch).
Multiply SR1 rate by 8/7.
Multiply SR1 rate by 10/7. SRX10D7 and SRX8D7 are mutually exclusive.
Modem filter enable (left channel only). Change only when DACs and ADCs are powered down.
ADC left sample generator select
0 = SR0 Selected (32h)
1 = SR1 Selected (2Ch).
DAC left sample generator select
0 = SR0 Selected (32h)
1 = SR1 Selected (2Ch).
Digital Mono Select.
0 = Mixer
1 = Left DAC and Right DAC.
Digital Audio Mode. DAC Outputs bypass analog mixer and sent directly to the codec output.
