ADC SUBMIT SETUP
By pressing the ‘ADC Setup’ button, the software writes to the device setting the
L/RLINE_IN1 through ADC to SPDIF_Out path active. As with the DAC setup described
previously, this is to ease the initial use of the WM8973 until the user becomes familiar with
both device and software operation. It should be noted that the SPDIF_In connection is still
required to provide the necessary clocks to the WM8973 in this mode.
