BITS
Digital Volume Slew Speed
0 = Digital volume changes are slewed over 10ms.
1 = Digital volume changes are slewed over 80ms.
Volume Change Smoothing
0 = Volume changes slew through all intermediate values.
1 = Volume changes occur in one step.
Line Input Zero-Crossing Detection
0 = Line input volume changes occur at zero crossings in the audio waveform or after 62ms if no zero
1 = Line-input volume changes occur immediately.
Jack Detection Enable
SHDN = 0: Sleep Mode
Enables pullups on LOUTP and JACKSNS/AUX to detect jack insertion. LSNS and JKSNS are valid.
LOUTP detection is only valid in differential and capacitorless output modes.
SHDN = 1: Normal Mode
Enables the comparator circuitry on JACKSNS/AUX to detect voltage changes. JKMIC is valid if the
microphone circuitry is enabled.
Note: AUXEN must be set to 0 for jack detection to function.
Headphone Amplifier Mode
Note: In mono operation, the right amplifier is disabled.
