GppIntensity

At power up, GppIntensity of each GPP pin is initialized with GpioIntensityOn or GpioIntensityOff depending on GpioOutPwrUp

corresponding bits value.

Only if Autolight is OFF, else must be left to 0 (default value)

GpioOutPwrUp must be set to OFF in Continuous Fading Mode (with Autolight OFF)

Only if Autolight is OFF, else ignored

In SPO mode assure the following settings: GpioOutPwrUp=OFF, GpioAutoLight=ON, GpioPolarity=Normal, GpioFunction=Linear
