(8 sensors) with LED Drivers and Analog Output
Default: 0x00000000
Enables pullup/down resistors for GPIO pins.
00 : None
01 : Pullup
10 : Pulldown
11 : Reserved
Default: 0x0000
Defines the Fading mode for GPO[7:0].
00: Single Fading Mode
01: Continuous Fading Mode
10: Reseved
11: Reserved
Default: 0x0000
The fading modes are expected to be
defined at power up by the QSM or NVM.
In case the fading modes need to be
changed after power up this can be done
when the GPOs are all OFF.
