Description
3 PCM_AMUTE PCM auto mute.
0 Function disabled
1 (Default) Mute occurs after reception of 8,192 consecutive audio samples of static 0 or –1. A single sample of
non-static data releases the mute. Detection and muting is done independently for each channel.
2
PCM_ Auto mute channel B equals channel A.
AMUTEBEQA _{0 (Default) Function disabled.}
1 Only mute when both channels AMUTE conditions are detected.
1 PCM_MUTE_ Channel A mute.
A
0 (Default) Function is disabled.
1 Channel output is muted. Muting function is affected by the PCM_SZC bits.
0 PCM_MUTE_ Channel A mute.
B
0 (Default) Function is disabled.
1 Channel output is muted. Muting function is affected by the PCM_SZC bits.

1 Signal polarity of channel A is inverted
2 PCM_INV_B Channel B signal invert.
0 (Default) the function is disabled
1 Signal polarity of channel B is inverted
1 PCM_SWAP_ Swap channels A and B at the input. This bit takes effect before PCM_COPY_CHAN.
CHAN
0 (Default) Function disabled
1 Enable channel A and B swapping
0 PCM_COPY_ Copy channel A to channel B. This bit takes effect after PCM_SWAP_CHAN.

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.
0 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.
