Digital Interface Format (DIF2:0) Bits 6-4
Function:
These bits select the interface format for the serial audio input.
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
De-Emphasis Control (DEM1:0) Bits 3-2
Default = 0
00 - No De-emphasis
01 - 44.1 kHz De-emphasis
