SW3: CODEC SETUP SWITCH
(Default: 1=OFF, 2=ON, 3=ON, 4=ON)
Connects or disconnects the audio oscillator
1-2 depending on how the system is setup.
See users manual for more information.
OFF = AD1835 is SLAVE
3
ON = AD1835 is MASTER
Disconnects ADC_DATA signal from
4 driving the corresponding DAI signal.
Useful if using this DAI pin for another purpose.
AUDIO_VREF_ADC
Disconnects Audio and SPI chip selects, also ALRCLK
