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

PDSTS Description

0 Power up/down is not complete.

Bit 6 — MIBPD

Microphone Bias Power Down. This is used to power up (set to 0) or power down (set to 1) the microphone bias

output.

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

OSCC Description

0 Crystal oscillator is off (default).

1 Crystal oscillator is on.

Bit 4 — BCKC
