6.2.3 PCM/DSD Selection (DSD/PCM)
Default = 0
0 - PCM
1 - DSD
Function:
This function selects DSD or PCM Mode. The appropriate data and clocks should be present before
changing modes, or else MUTE should be selected.
6.2.4 DAC Pair Disable (DACx_DIS)
Default = 0
0 - DAC Pair x Enabled
1 - DAC Pair x Disabled
Function:
When the bit is set, the respective DAC channel pair (AOUTAx and AOUTBx) will remain in a reset state.
It is advised that changes to these bits be made while the power-down (PDN) bit is enabled to eliminate
the possibility of audible artifacts.
6.2.5 Power Down (PDN)
Default = 1
0 - Disabled
1 - Enabled
Function:
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 in Control Port Mode can occur.

6.3.1 Digital Interface Format (DIF)
Default = 0000 - Format 0 (Left-Justified, up to 24-bit data)
Function:
These bits select the interface format for the serial audio input. The DSD/PCM bit determines whether
PCM or DSD Mode is selected.
The required relationship between the Left/Right clock, serial clock and serial data is defined by the Digital
Interface Format and the options are detailed in Figures 8 through 15 .
Note:
While in PCM Mode, the DIF bits should only be changed when the power-down (PDN) bit is set
to ensure proper switching from one mode to another.
