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