SLES092D – APRIL 2010 – REVISED AUGUST 2015

The OVER bit is used to control the oversampling rate of the delta-sigma D/A converters. The OVER = 1 setting

is recommended when the sampling rate is 192 kHz (system clock rate is 128 fS or 192 fS).

8.6.1.2.4

SRST: Reset

Default value: 0

The SRST bit is used to enable or disable the soft reset function. The operation is the same as power-on reset.

All registers are initialized.

8.6.1.2.5

DACx: DAC Operation Control

Where x = 1 or 2, corresponding to the DAC output VOUTL (x = 1) or VOUTR (x = 2).

Default value: 0

The DAC operation controls are used to enable and disable the DAC outputs, VOUTL and VOUTR. When DACx =

0, the corresponding output generates the audio waveform dictated by the data present on the DATA pin. When

DACx = 1, the corresponding output is set to the bipolar zero level, or 0.5 VCC.

8.6.1.2.6

DM12: Digital De-Emphasis Function Control

Default value: 0

The DM12 bit is used to enable or disable the digital de-emphasis function. See the plots shown in the Typical

Characteristics section of this data sheet.

8.6.1.2.7

DMF[1:0]: Sampling Frequency Selection for the De-Emphasis Function

Default value: 00

The DMF[1:0] bits are used to select the sampling frequency used for the digital de-emphasis function when it is

enabled.
