If ‘1’, headphone driver is enabled.
If ‘1’, de-emphasis is enabled when the sample rate is
48, 44.1 or 32 kHz.
If ‘1’, DC filter is enabled.
If ‘1’, activate high-pass filter in the decimator.
If ‘1’, the following interrupt/wake-up signalling is enabled:
Interrupt signalling via GPIO_INT (input slot 12) when
BIT_CLK is on.
Wake-up signalling via SDATA_IN when BIT_CLK is off.
Reserved.
When read, returns ADC overflow status (set status is
sticky until cleared).
When written, clears ADC overflow status.
