        Configure GVDD level, which is a reference level for the VCOM level and
        the grayscale voltage level. GVDD should be ≦ (AVDD - 0.5) V .

        Configure the high level of VCOM AC voltage. VCOM needs to be adjusted
        to match the capacitance and performance specifications of the TFT panel
        to maximize contrast and minimize flickering

    help
        Enable this configuration to convert little endian colors to big endian.
        ILI9341 device requires colors to be send in big endian RGB-565 format.
        Enabling this option allows for little endian colors. Enabling this
        however will slow down the driver as it cannot use DMA anymore.
