Headphone amplifier settings
Using a 1-bit value, it is possible to disable the short-circuit protection of the headphone amplifier. This function is
provided to offer maximum freedom to users, however due to the nature of this function there is the drawback of possible
damage. Bits RSV12, RSV11, RSV10, RSV02, RSV01, and RSV00 are special control bits for manufacturer’s evaluation
and must always be kept at their default values for normal operation of UDA1380.

Short circuit protection enable. A 1-bit value to enable the short circuit protection of the
headphone amplifier. When this bit is set to logic 0: short-circuit protection is disabled.
When this bit is set to logic 1: short-circuit protection is enabled. Default value 1.
Short-circuit detection is always enabled regardless of this bit.
