DSD Control (address 04h)
Default = 11
00 - Single-Speed Mode (4 to 50 kHz sample rates)
01 - Double-Speed Mode (50 to 100 kHz sample rates)
10 - Quad-Speed Mode (100 to 200 kHz sample rates)
11 - Auto Speed Mode detect (32 kHz to 200 kHz sample rates)
Function:
Selects the required range of input sample rates or Auto Speed Mode.
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.
The DSD/PCM bit determines whether PCM or DSD Mode is selected.
