By setting MUTx = 0, the attenuator is increased one step for every 8/f
S
seconds to the previously programmed
attenuation level.

oversampling
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 f
S
or 192 f
S
).
SRST: Reset
Default value: 0
SRST = 0
SRST = 1
Reset disabled (default)
Reset enabled
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.

R. 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 V

De-emphasis disabled (default)
De-emphasis enabled
The DM12 bit is used to enable or disable the digital de-emphasis function. See the plots shown in the
