ADPT_PWR Adaptive power adjustment. Configures how power to line output amplifiers adapts to the output signal level.

000 Reserved

001 Fixed, Mode 0 (±VP_LDO)

010 Fixed, Mode 1 (±VCP)

011–110 Reserved

111 (Default) Adapt to signal. The output signal dynamically determines the voltage level.

HV_EN

High voltage mode enable.

0 Function disabled (VP_LDO = 2.6V)

1 (Default) Function enabled (VP_LDO = 3.0 V). This requires VP min to be 3.3 V. Also, this mode only applies to

load 600

 and above.

EXT_VCPFILT External VCP_FILT± voltage mode.

0 (Default) Function disabled

1 When enabled, VCP_FILT± voltages can be provided externally at ±3.0 V. See power sequencing/timing

requirement in related functional description.

HPDETECT_

CTRL

HP detect control. Configures operation of the HP detect circuit. The internal weak current source pull-up is enabled in

all modes.

00 (Default) Disabled. The HP detect digital circuit is powered down and does not report to the status registers

(HPDETECT_PLUG_INT and HPDETECT_UNPLUG_INT are also cleared).

11 Enabled

HPDETECT_

INV

HP detect invert. Can be used to invert the signal from the HP detect circuit.

0 (Default) Not inverted
