These bits control the overall bias current of the headphone
amplifier (all stages including first and output stage).
0x0=nominal, 0x1=-50%, 0x2=+50%, 0x3=-40%
These bits control the bias current for the first stage of the
headphone amplifier.
0x0=nominal, 0x1=-50%, 0x2=+100%, 0x3=+50%
These bits control the headphone output current in classA
mode and also the pulldown strength while powering off.
These bits will normally not be needed.
This defaults high. When this bit is high the headphone is in
classAB mode. ClassA mode would normally not be used.
This defaults high. When this bit is high and the capless
headphone center channel is powered off the output will be
tied to ground. This is the preferred mode of operation for best
antipop performance.
This defaults high. When this bit is high and the headphone is
powered off the output will be tied to ground. This is the
preferred mode of operation for best antipop performance.
Double the VAG output current when in classA mode.
Turn off the classAB output current for the VAG buffer. The
classA current is limited so this may cause clipping in some
modes.
Put ADCmux output onto the headphone output pin. Must
remove headphone load and any external headphone
compensation for this mode.
Enable headphone common to be used in ADCmux for
testing
Enable the mic-adc-dac-HP path
