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 is detected, device limits
the
the maximum current to the load.
1: If short-circuit protection is enabled for headphone driver and short circuit is detected, device powers
down the output driver.
D0 R 0 0: Short circuit is not detected on the headphone driver.
