The ADC will enter a low-power state when this function is enabled.
Default = 0
0 - Disabled
1 - Enabled
The internal high-pass filter is defeated when this function is enabled. Control of the internal high-
pass filter is independent for the left and right channel.
Default = 0
0 - Disabled
1 - Enabled
The output for the selected ADC channel will be muted when this function is enabled.
Default = 0
0 - Disabled
1 - Enabled
The device will automatically perform an offset calibration when brought out of reset, which last ap-
proximately 50 ms. When this function is enabled, a rising edge on the reset line will initiate an offset
calibration.
Default = 0
0 - Calibration done
1 - Calibration in progress
