Functional Mode (address 03h)
DAC FUNCTIONAL MODE (DAC_FMX)
Selects the required range of sample rates for all converters clocked from the DAC serial port (DAC_SP).
Bits must be set to the corresponding sample rate range when the DAC_SP is in Master or Slave Mode.

11 - Reserved
Function:
When enabled, the PLL is held in a reset state. It is advised that any change of this bit be made while
the DACs are muted or the power-down bit (PDN) is enabled to eliminate the possibility of audible
artifacts.
When enabled the stereo analog to digital converter will remain in a reset state. It is advised that any
change of this bit be made while the DACs are muted or the power-down bit (PDN) is enabled to elim-
inate the possibility of audible artifacts.
When enabled the respective DAC channel pair x (AOUTAx and AOUTBx) will remain in a reset state.
The entire device will enter a low-power state when this function is enabled, and the contents of the
control registers are retained in this mode. The power-down bit defaults to ‘enabled’ on power-up and
must be disabled before normal operation can occur.
