Global Shutdown. Disables everything except the headset detection circuitry, which is
controlled separately.
0 = Device Shutdown

Performance Mode. Selects DAC to headphone playback performance mode.
0 = High performance playback mode
1 = Low power playback mode..
power playback when using DAC to headphone playback path only. When enabled,
this bit overrides the System Bias Control register settings. When disabled, the System
Bias Control register is used to enable system bias blocks. Set both HPPLYBCK and
PERFMODE for lowest power consumption when using DAC to headphone playback
path only.
0 = Disabled
1 = Enabled.
8kHz Power Save Mode. PWRSV8K configures the ADC for reduced power
consumption when f

0 = Normal, high-performance mode.
1 = Low power mode.
Power Save Mode. PWRSV configures the ADC for reduced power consumption for
all sample rates. PWRSV can be used in conjunction with PWRSV8K for more power
savings.
