    help
        Configure the AVDD voltage for analog circuits in millivolts.
        Valid values must be in the range of 4500 (4.5V) to 5100 (5.1V)
        in steps of 100.

        Configure the GVDD voltage, the gamma reference positive voltage.
        Valid values must be in the range of 3150 (3.15V) to 4700 (4.7V)
        in steps of 50.

        Configure the VCOM voltage. VCOM needs to be adjusted to match the
        capacitance and performance specifications of the TFT panel to
        maximize contrast and minimize flickering.
        Valid values must be in the range of -2000 (-2.0V) to -425 (-0.425V)
        in steps of 25.
