SW7: 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

4driving the corresponding DAI signal.

Useful if using this DAI pin for another purpose.
