Bit 11 — MOPD
Mono Driver Power Down. This is used to power up (set to 0) or power down (set to 1) the mono output driver. If
only playback of the line or Mic inputs through the mono output is needed, the user need only power up the
mono section, and not the DAC or ADCs. The line inputs, Mic preamp, left channel ADC multiplexer and left
channel volume control all power up if the mono output is powered up. The default is 1 (powered down).
Bit 10 — DAPD
DAC Power Down. This is used to power up (set to 0) or power down (set to 1) the entire stereo DAC. The
default is 1 (powered down).
Bit 9 — ADPDL
Left Channel ADC Power Down. This is used to power up (set to 0) or power down (set to 1) the entire left
channel ADC. The line inputs, Mic preamp, left channel ADC multiplexer and left channel volume control all
automatically power up when the left channel ADC is powered up. The default is 1 (powered down).
Bit 8 — ADPDR
Right Channel ADC Power Down. This is used to power up (set to 0) or power down (set to 1) the entire right
channel ADC. The line inputs, Mic preamp, right channel ADC multiplexer and right channel volume control all
automatically power up when the right channel ADC is powered up. The default is 1 (powered down).
Bit 7 — PDSTS
Power Up/Down Done. This read-only bit indicates that all power-up or power-down processes requested are
completed.
Table 49. Power Up/Down Flag

output.
Table 50. Microphone Bias Power Down
OSCC
Description
0
Microphone bias is on.
1
Microphone bias is off (default).
Bit 5 — OSCC
Crystal Oscillator Control. This bit turns ON/OFF the crystal Oscillator.
Table 51. Crystal Oscillator Control
