These registers define the mapping between the GPO pins (with Autolight ON) and the sensor information
which will control its ON/OFF state.
The mapping can be done to a specific sensor event but also on groups (in this case any sensor event in the
group will control the GPO).

Several GPOs can be mapped to the same sensor
event and will be controlled simultaneously.
Defines Group0 sensor events:
0: OFF
1: ON
If any of the enabled sensor events occurs the
Group0 event will occur as well.
All sensors events within the group can be
independently set.
Default: 0x00
Defines Group1 sensor events:
0: OFF
1: ON
If any of the enabled sensor events occurs the
Group0 event will occur as well.
All sensors events within the group can be
independently set.
Default: 0x00
