6.1.3
DE-EMPHASIS CONTROL (DEM) BIT 3-2
Default = 00
00 - Disabled
01 - 44.1 kHz
10 - 48 kHz
11 - 32 kHz
Function:
Selects the appropriate digital filter to maintain the standard 15 µs/50 µs digital de-emphasis filter re-
sponse at 32, 44.1 or 48 kHz sample rates. (See Figure 35.)
Note: De-emphasis is only available in Single-Speed Mode.

FUNCTIONAL MODE (FM) BIT 1-0
Default = 00
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 - Reserved
Function:
Selects the required range of input sample rates.
