SRST = 0
SRST = 1
Re-synchronization
Normal operation (default)
The SRST bit controls system reset. The PCM3052A does not go into power-down state. The mode control
register is not reset by this control. Also pop-noise may be generated.
Default value: 0
ADPSV = 0
ADPSV = 1
Normal operation (default)
Power-save mode
The ADPSV bit controls ADC power-save mode. In power-save mode, ADC goes into power-down state, the
data in ADC are reset, and DOUT is forced into ZERO immediately. I
2
C control is enabled.
Default value: 0
DAPSV = 0
DAPSV = 1
Normal operation (default)
Power-save mode
The DAPSV bit controls the DAC power-save mode. In the power-save mode, the DAC output is faded out and
DAC goes into the power-down state. I
2
C control is enabled. A waiting time of more than 2100/f
S
from
power-save-mode assertion is required for the release of the power-save mode.
DIT function is available if SPDIF bit = 1, even though DAPSV = 1.

oversampling
The OVR1 bit is used to control the oversampling rate of the delta-sigma D/A converters. To write over this
register during normal operation may generate noise.

Default value: 0

Mute disabled (default)
Mute enabled
The mute bits, MUT1 and MUT2, are used to enable or disable the soft-mute function for the corresponding DAC
outputs, V
OUT
L and V
OUT
R. The soft-mute function is incorporated into the digital attenuators. When mute is
disabled (MUTx = 0), the attenuator and DAC operate normally. When mute is enabled by setting MUTx = 1, the
digital attenuator for the corresponding output is decreased from the current setting to infinite attenuation, one
attenuator step (0.5 dB) for every 8/f
S
seconds. This provides
pop-free
muting of the DAC output.
By setting MUTx = 0, the attenuator is increased one step for every 8/f
S
seconds to the previously programmed
attenuation level.
