CS4384
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 9-21.

5.4.1
DSD Mode Digital Interface Format (DSD_DIF)
Default = 000 - Format 0 (64x oversampled DSD data with a 4x MCLK to DSD data rate)
Function:
The relationship between the oversampling ratio of the DSD audio data and the required Master clock to
DSD data rate is defined by the Digital Interface Format pins.
