00b

ADC2 Channel Mode[1:0]: Controls the chan-
nel mapping from the ADC2 output to the HDA
bus.
‘00’b - ADC2 left channel is mapped to HDA left
channel and ADC2 right channel is mapped HDA
right channel (normal mode).
‘01’b - ADC2 left channel is mapped to both HDA
left and right channels. ADC2 right channel is
discarded (mono mode).
‘10’b - ADC2 right channel is mapped to both
HDA left and right channels. ADC2 left channel is
discarded (alternate mono mode).
‘11’b - ADC2 left channel is mapped to HDA right
channel and ADC2 right channel is mapped to
HDA left channel (channel swap mode).

ADC1 Channel Mode[1:0]: Controls the chan-
nel mapping from the ADC1 output to the HDA
bus.
‘00’b - ADC1 left channel is mapped to HDA left
channel and ADC1 right channel is mapped HDA
right channel (normal mode).
‘01’b - ADC1 left channel is mapped to both HDA
left and right channels. ADC1 right channel is
discarded (mono mode).
‘10’b - ADC1 right channel is mapped to both
HDA left and right channels. ADC1 left channel is
discarded (alternate mono mode).
‘11’b - ADC1 left channel is mapped to HDA right
channel and ADC1 right channel is mapped to
HDA left channel (channel swap mode).
