This bit is high whenever a short is detected on the left or right channel headphone
drivers.
0x0 = Normal
0x1 = Short detected
This bit is high whenever a short is detected on the capless headphone common/
center channel driver.
0x0 = Normal
0x1 = Short detected
Reserved
This bit goes high after the PLL is locked.
0x0 = PLL is not locked
0x1 = PLL is locked
Reserved
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 pull-down
strength while powering off. These bits will normally not be needed.
