This programs the input level of the data arriving from the right DAC's interpolator output.
This selects which input is fed to the Left TX Channel of Audio Port 1.
This selects which input is fed to the Right TX Channel of Audio Port 1.
If set, this swaps the Left and Right outputs to Audio Port 1.
If set, the right channel is ignored and the left channel becomes (left+right)/2.
This selects which input is fed to Audio Port 2's Left TX Channel.
This selects which input is fed to Audio Port 2's Right TX Channel.
If set, this swaps the Left and Right outputs to audio port 2.
If set, the right channel is ignored and the left channel becomes (left+right)/2.
