Enable/Disable the DAP mixer path
0x0 = Disable
0x1 = Enable
When enabled, DAP_EN must also be enabled to use the mixer.
Reserved
Enable/Disable digital audio processing (DAP)
0x0 = Disable. When disabled, no audio will pass-through.
0x1 = Enable. When enabled, audio can pass-through DAP even if none of the DAP
functions are enabled.
These bits control the behavior of the short detector for the capless headphone central
channel driver. This mode should be set prior to powering up the headphone amplifier.
When a short is detected the amplifier output switches to classA mode internally to
avoid excessive currents.
0x0 = Disable short detector, reset short detect latch, software view non-latched short
signal
0x1 = Enable short detector and reset the latch at timeout (every ~50 ms)
0x2 = This mode is not used/invalid
0x3 = Enable short detector with only manual reset (have to return to 0x0 to reset the
latch)

When a short is detected the amplifier output switches to classA mode interally to avoid

0x0 = Disable short detector, reset short detect latch, software view non-latched short
signal
0x1 = Enable short detector and reset the latch at timeout (every ~50 ms)
0x2 = Enable short detector and auto reset when output voltage rises (preferred mode)
0x3 = Enable short detector with only manual reset (have to return to 0x0 to reset the
latch)
