6.1.3
DE-EMPHASIS CONTROL (DEM) BIT 2-3
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 18.)
Note: De-emphasis is only available in Single-speed Mode.
6.1.4
FUNCTIONAL MODE (FM) BIT 0-1
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.
