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 the L2 comparator.
1 = the L2 comparator is enabled for the CMP_IN comparator.
0 = the L2 comparator is disabled for the CMP_IN comparator.
