4.3.1 ATAPI CHANNEL MIXING AND MUTING (ATAPI)
Default = 1001 - AOUTAx = L, AOUTBx = R (Stereo)
Function:
The CS4360 implements the channel mixing functions of the ATAPI CD-ROM specification. Refer to
Table 2 and Figure 24 for additional information.
Note: All mixing functions occur prior to the digital volume control. Mixing only occurs in channel pairs.

4.4.1 MUTE (MUTE)
Default = 0
0 - Disabled
1 - Enabled
Function:
The Digital-to-Analog converter output will mute when enabled. The quiescent voltage on the output
will be retained. The muting function is effected, similar to attenuation changes, by the Soft and Zero
Cross bits. The MUTEC pin will go active during the mute period if the Mute function is enabled for
both channels in the pair.
