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.
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.
