Description

FILT

7:5

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_RD

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.

L3_OUT

This bit is the output of the L3 comparator.

L2_OUT

This bit is the output of the L2 comparator.

L3_EN

1 = the L3 comparator is enabled for the CMP_IN comparator.

0 = the L3 comparator is disabled for the CMP_IN comparator.

L2_EN

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.

FILT2

7:5

Filter setting for the CMP_IN2 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_RD2

Force a read of the CMP_IN2 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.

L3_OUT2

This bit is the output of the L3 comparator for the second light sensor.

L2_OUT2

This bit is the output of the L2 comparator for the second light sensor.

L3_EN2

1 = the L3 comparator is enabled for the CMP_IN2 comparator.

0 = the L3 comparator is disabled for the CMP_IN2 comparator.
