Register 64 0 1 0 0 0 0 0 0 MRST SRST ADPSV DAPSV RSV RSV RSV S/E
MRST: Mode Control Register Reset (ADC and DAC)
Default value: 1
MRST = 0 Set default value
MRST = 1 Normal operation (default)
The MRST bit controls reset of the mode control registers to their default values. Pop noise may be generated.
Returning the MRST bit to 1 is not required, as the MRST bit is automatically set to 1 after a mode control
register reset.
SRST: System Reset (ADC and DAC)
Default value: 1
SRST = 0 Resynchronization
SRST = 1 Normal operation (default)
The SRST bit controls system reset, the relation between system clock and sampling clock is re-synchronized,
and ADC operation and DAC operation is restarted. The mode control register is not reset and the PCM3060
does not go into power down state, but pop-noise may be generated. Returning the SRST bit to 1 is not required,
as the SRST bit is automatically set to 1 after triggering a system reset.
ADPSV: ADC Power-Save Control (ADC)
Default value: 1
ADPSV = 0 Normal operation
ADPSV = 1 Power-save mode (default)
The ADPSV bit controls the ADC power-save mode. In power-save mode, DOUT is forced to ZERO with a
fade-out sequence, the internal ADC data are reset, and the ADC goes into the power-down state. For
power-save mode release, a fade-in sequence is applied on DOUT during the resume process. The serial mode
control is enabled during this mode. A waiting time of more than 2048/f
S
is required for the proper status change
by this power save control on/off. As the default state after power on is the power-save mode and DOUT is
disabled (ZERO), release from the power-save mode is required for normal operation. The detailed sequence
and timing for ADPSV control is shown Figure 22 and Figure 23 .
NOTE:
It is recommended that changing/stopping clocks or changing the audio interface
mode be performed in power-down mode in order to avoid unexpected pop/click noise
and performance degradation.
