Description
Filter setting for the CMP_IN light sensor.
000 = 80 ms.
001 = 160 ms.
010 = 320 ms.
011 = 640 ms.
100 = 1280 ms.
101 = 2560 ms.
110 = 5120 ms.
111= 10,240 ms.
Force a read of the CMP_IN light sensor while independent sinks are running, but the backlight is not. Reset by chip
after the conversion is complete and L2_OUT and L3_OUT are valid. Ignored if the backlight is enabled.
This bit is the output of the L3 comparator.
This bit is the output of the L2 comparator.
1 = the L3 comparator is enabled for the CMP_IN comparator.
0 = the L3 comparator is disabled for the CMP_IN comparator.
Note that the L3 comparator has priority over L2.
1 = the L2 comparator is enabled for the CMP_IN comparator.
0 = the L2 comparator is disabled for the CMP_IN comparator.
