Channel Invert (address 14h)
Default = 0
0 - Disabled
1 - Enabled
Function:
The PWM outputs of the CS44600 will mute when enabled. The muting function is affected, similar to at-
tenuation changes, by the Soft and Zero Cross bits (SZC[1:0]).
Default = 0
0 - Disabled
1 - Enabled
Function:
When enabled, these bits will invert the signal polarity of their respective channels.
