4 Description:
5                 Dither enable. Write 1 to enable dither or 0 to disable it. This is useful
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

15 Description:
16                 This raw, unscaled value refers to the dither signal amplitude.
17                 The same scale as in out_voltageY_raw applies. However, the
18                 offset might be different as it's always 0 for this attribute.
