Invert Control (address 05h)
Mixing Control Pair 1 (Channels A1 & B1)(address 06h)
Mixing Control Pair 2 (Channels A2 & B2)(address 09h)
Mixing Control Pair 3 (Channels A3 & B3)(address 0Ch)
Mixing Control Pair 4 (Channels A4 & B4)(address 0Fh)
Default = 0
0 - Disabled
1 - Enabled
Function:
When enabled, these bits will invert the signal polarity of their respective channels.
Default = 0
0 - Disabled
1 - Enabled
Function:
The AOUTAx and AOUTBx volume levels are independently controlled by the A and the B Channel Volume
Control Bytes when this function is disabled. The volume on both AOUTAx and AOUTBx are determined
by the A Channel Attenuation and Volume Control Bytes (per A-B pair), and the B Channel Bytes are ig-
nored when this function is enabled.
Default = 01001 - AOUTAx=aL, AOUTBx=bR (Stereo)
Function:
The
functions are applied per A-B pair. Refer to Table 7 and Figure 14 for additional information.
