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.
