11: Output common-mode voltage = 1.8 V
D2 R/W 1 Reserved. Write only 1 to this bit.
D1 R/W 0 0: If short-circuit protection is enabled for headphone driver and short circuit detected, device limits the
maximum current to the load.
1: If short-circuit protection is enabled for headphone driver and short circuit detected, device powers
down the output driver.
