This feature allows the user to select whether the DAC interpolation filter has a fast- or slow roll-off.
For filter characteristics, please See
0 - Fast roll-off.
1 - Slow roll-off.
When this bit is set, the internal high-pass filter for the selected channel will be disabled. The current
DC offset value will be frozen and continue to be subtracted from the conversion result. See

In Master Mode, DAC_SCLK and DAC_LRCK are outputs. Internal dividers will divide the master
clock to generate the serial clock and left/right clock. In Slave Mode, DAC_SCLK and DAC_LRCK
become inputs.
If the DAC_SP is in Slave Mode, DAC_LRCK must be present for proper device operation.
In Master Mode, ADC_SCLK and ADC_LRCK are outputs. Internal dividers will divide the master
clock to generate the serial clock and left/right clock. In Slave Mode, ADC_SCLK and ADC_LRCK
become inputs.
If the ADC_SP is in Slave Mode, ADC_LRCK must be present for proper device operation.
To use the PLL to lock to ADC_LRCK, the ADC_SP must be in Slave Mode. When using the PLL to
lock to LRCK, if ADC_SDOUT is configured to be clocked by the ADC_SP, both ADC_SCLK and
ADC_LRCK must be present. If ADC_SDOUT is configured to be clocked by the DAC_SP, only the
ADC_LRCK signal must be applied.
