AOUTx Volume Control:
AOUTA (Address 16h) & AOUTB (Address 17h)
AOUTX Volume Control (AOUTX_VOL[7:0])
Default = 00h
Function:
The analog output levels can be adjusted in 0.5 dB increments from +12 to -102 dB as dictated by the DAC
Soft and Zero Cross bits (DACX_SZC[1:0]). Levels are decoded in unsigned binary as described in the table
above.
Note:
PCM Channel Mixer (Address 18h)
Channel Mixer (PCMx[1:0])
Default: 00
Function:
Implements mono mixes of the left and right channels as well as a left/right channel swap.

When the limiter is enabled, the AOUT Volume is automatically controlled and should not be ad-
justed manually. Alternative volume control may be achieved using the PCMMIXx_VOL[6:0] bits.
