CS43L21
Function:
These bits select the gain multiplier for the headphone/line outputs. See
“Line Output Voltage Characteris-
tics” on page 14
and
“Headphone Output Power Characteristics” on page
15.
DAC Single Volume Control (DAC_SNGVOL)
Default: 0
Function:
The individual channel volume levels are independently controlled by their respective Volume Control reg-
isters when this function is disabled. When enabled, the volume on all channels is determined by the AOU-
TA Volume Control register and the AOUTB Volume Control register is ignored.
PCMX Invert Signal Polarity (INV_PCMX)
Default: 0
0 - Disabled
1 - Enabled
Function:
When enabled, this bit will invert the signal polarity of the PCM x channel.
DACX Channel Mute (DACX_MUTE)
Default: 0
0 - Disabled
1 - Enabled
Function:
The output of channel x DAC will mute when enabled. The muting function is affected by the DACx Soft and
Zero Cross bits (DACx_SZC[1:0]).
