PSVAD[2:0] ADC Power-save control
These bits control the ADC power-save mode. In power-save mode, DOUT is forced into ZERO
with a fade-out sequence, the internal ADC data are reset, and the ADC goes into a power-down
state. For power-save mode release, a fade-in sequence is applied on DOUT in resume process.
The serial mode control is enabled during this mode. Wait times greater than tADCDLY2 are
required for the status change because of the power-save control turning on/off.
Default value: 000.

ADC HPF bypass control
These bits control the HPF function and dc components of the input signal; internal dc offset is
converted in bypass mode.
