DMF[1:0] DE-EMPHASIS SAMPLING RATE SELECTION
0 0 44.1 kHz
0 1 48 kHz (default)
1 0 32 kHz
1 1 Reserved
The DMF[1:0] bits are used to select the sampling frequency used for the digital de-emphasis function when it is
enabled.
Default value: 0
DM12 = 0 De-emphasis disabled (default)
DM12 = 1 De-emphasis enabled
The DM12 bit is used to enable or disable the digital de-emphasis function. See the plots shown in the Typical
Performance Curves section of this data sheet.
