This selects which input is fed to the left ADC's decimator input.
This selects which input is fed to the right ADC's decimator input.
This selects sets the source of the Digital Mixer Clock. The 'Auto' setting will automatically select the source
with the highest clock frequency. If the DAC interpolator output (DAC_OSR_L or DAC_OSR_R) is
selected, then MXR_CLK_SEL should be set to '10'.
This adds Audio Port 1's left RX channel to the DAC's left input.
This adds Audio Port 2's left RX channel to the DAC's left input.
This adds the ADC's left output to the DAC's left input.
This adds Audio Port 1's right RX channel to the DAC's right input.
This adds Audio Port 2's right RX channel to the DAC's right input.
This adds the ADC's right output to the DAC's right input.
If set, this swaps the Left and Right inputs to the DAC.
