6 for changing the dither parameters. They way it should be done is:
8 - disable dither operation;
9 - change dither parameters (eg: frequency, phase...);
10 - enabled dither operation
16 This raw, unscaled value refers to the dither signal amplitude.
24 Available range for dither raw amplitude values.
37 Sets the dither signal frequency. Units are in Hz.
43 Returns the available values for the dither frequency.
49 Sets the dither signal phase. Units are in Radians.
