6.3.2 Functional Mode (FM)
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.
6.4 DSD Control (Address 04h)
6.4.1 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.
The DSD/PCM
bit determines whether PCM or DSD Mode is selected.
