Table 14. Register 0x06, Level 1 (Daylight) Dim Current (DAYLIGHT_DIM)
Bit Mnemonic R/W Description
7 Unused.
6 to 0 DAYLIGHT_DIM R/W
Dim current setting for the backlight when BL_LVL is at Level 1 (daylight). See Figure 16 for
backlight current vs. sink code relationship.
Table 15. Register 0x07, Level 2 (Office) Maximum Current (OFFICE_MAX)
Bit Mnemonic R/W Description
7 Unused.
6 to 0 OFFICE_MAX R/W
Maximum current setting for the backlight when BL_LVL is at Level 2 (office). See Figure 16 for
backlight current vs. sink code relationship.
Table 16. Register 0x08, Level 2 (Office) Dim Current (OFFICE_DIM)
Bit Mnemonic R/W Description
7 Unused.
6 to 0 OFFICE_DIM R/W
Dim current setting for the backlight when BL_LVL is at Level 2 (office). See Figure 16 for
backlight current vs. sink code relationship.
Table 17. Register 0x09, Level 3 (Dark) Maximum Current (DARK_MAX)
Bit Mnemonic R/W Description
7 Unused.
6 to 0 DARK_MAX R/W
Maximum current setting for the backlight when BL_LVL is at Level 3 (dark). See Figure 16 for
backlight current vs. sink code relationship.
Table 18. Register 0x0A, Level 3 (Dark) Dim Current (DARK_DIM)
Bit Mnemonic R/W Description
7 Unused.
6 to 0 DARK_DIM R/W
Dim current setting for the backlight when BL_LVL is at Level 3 (dark). See Figure 16 for
backlight current vs. sink code relationship.
Table 19. Register 0x0B, Backlight Current Value (BL_VALUE)
Bit Mnemonic R/W Description
7 Unused.
6 to 0 BL_VALUE R Read-only register. Contains the present value to which the backlight is programmed.
Table 20. Register 0x0C, Light Sensor Comparator Configuration (ALS_CMPR_CFG)
Bit Mnemonic R/W Description
7 to 5 FILT R/W 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 when the conversion is complete.
3 L3_OUT R 0 = ambient light is greater than Level 3 (dark).
1 = L3_CMPR 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 = L2_CMPR 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.
