PCMX Mixer Volume Control:
PCMA (Address 10h) & PCMB (Address 11h)
PCMX Mixer Channel Mute (MUTE_PCMMIXX)
Default = 1
0 - Disabled
1 - Enabled
Function:
The PCM channel X input to the output mixer will mute when enabled. The muting function is affected by
the DACX Soft and Zero Cross bits (DACX_SZC[1:0]).
PCMX Mixer Volume Control (PCMMIXX_VOL[6:0])
Default: 000 0000
Function:
The level of the PCMX input to the output mixer can be adjusted in 0.5 dB increments as dictated by the
DACX Soft and Zero Cross bits (DACX_SZC[1:0]) from +12 to -51.5 dB. Levels are decoded as described
in the table above.
