The OS bits change the oversampling rate of delta-sigma modulation. Use of this function enables the designer to
stabilize the conditions at the post low-pass filter for different sampling rates. As an application example,
programming to set 128 times in 44.1-kHz operation, 64 times in 96-kHz operation, and 32 times in 192-kHz operation
allows the use of only a single type (cutoff frequency) of post low-pass filter. The 128 fS oversampling rate is not
available at sampling rates above 100 kHz. If the 128 fS oversampling rate is selected, a system clock of more than
256 fS is required.
In DSD mode, these bits select the speed of the bit clock for DSD data coming into the analog FIR filter.
