• Power—Configures the power down controls and supply settings.
• MCLK—Controls for MCLK configuration.
• ASP—Settings for Audio Serial Port configuration.
• DMIC—Settings for digital mic configuration.

the sync protocol).
• Mic Bias—Power down and output voltage controls for the mic bias outputs.
• MUTE—Configures the polarity of the MUTE input pin and the associated power down states which are active while
MUTE is asserted.
• Input Pin Bias—Configures the bias for each input pin.
• Refresh—Reads all registers in all devices and updates the values in the FlexGUI.
