Power up the PLL VCO amplifier.
0x0 = Power down
0x1 = Power up
Power up the VAG reference buffer. Setting this bit starts the power up ramp for the
headphone and lineout. The headphone (and/or lineout) powerup should be set
BEFORE clearing this bit. When this bit is cleared the powerdown ramp is started. The
headphone (and/or lineout) powerup should stay set until the VAG is fully ramped
down (200 to 400 ms after clearing this bit).
0x0 = Power down
0x1 = Power up
While ADC_POWERUP is set, this allows the ADC to be put into left only mono
operation for power savings. This mode is useful when only using the microphone
input.
0x0 = Mono (left only)
0x1 = Stereo
Power up the reference bias currents
0x0 = Power down
0x1 = Power up
This bit can be cleared when the part is a sleep state to minimize analog power.
