Table 19. Register 0x0C, Light Senso r Comparator Configuration (ALS_CMPR_CFG)
Bit
7 to 5
Name
FILT
R/W
R/W
Description
Light sensor filter time.
000 = 0.08 sec.
001 = 0.16 sec.
010 = 0.32 sec.
011 = 0.64 sec.
100 = 1.28 sec.
101 = 2.56 sec.
110 = 5.12 sec.
111 = 10.24 sec.
4
FORCE_RD
R/W
Forces the light sensor comparator to perform a single conversion.
This bit is cleared by the internal state machine once the conversion is complete.
3
L3_OUT
R
0 = ambient light is greater than Level 3 (dark).
1 = the light sensor comparator has detected a change in ambient light from Level 2 (office) to Level
3 (dark).
2
L2_OUT
R
0 = ambient light is greater than Level 2 (office).
1 = the light sensor comparator has detected a change in ambient light from Level 1 (daylight) to
Level 2 (office).
1
L3_EN
R/W
0 = disable Comparator L3_CMPR .
1 = enable Comparator L3_CMPR. If automatic backlight adjustment is required, BL_AUTO_ADJ
must be set also.
0
L2_EN
R/W
0 = disable Comparator L2_CMPR.
1 = enable Comparator L2_CMPR. If automatic backlight adjustment is required, BL_AUTO_ADJ
must be set also.
Table 20. Register 0x0D, Level 2 (Office) Comparator Trip Point (L2_TRIP)
Bit
6 to 0
Name
L2_TRIP
R/W
R/W
Description
Sets the trip value for Comparator L2_CMPR. If ambient light levels fall below this trip point, L2_OUT
is set. Each code is equal to 4 μA (typical). Full scale is 1000 μA (typical).
