Mute/Invert Control (Address 5Bh)
Default = 0
Function:
When set, the signal polarity of the ADC will be inverted.
Default = 0
Function:
When set, the respective channel’s power and logic-level PWM output signal polarity will be inverted. The
serial output on the auxiliary and delay ports are unaffected.
Default = 0
Function:
When set, the Sub channel’s power and logic-level PWM output polarity will be inverted. The serial output
on the auxiliary port is unaffected.
Default = 0
Function:
The output of the ADC will mute when enabled.
Default = 0
Function:
The respective channel’s power PWM, logic-level PWM, and auxiliary serial data outputs will enter a mute
state when enabled. The delay serial output will be unaffected if the delay port is enabled. The muting
