Description
Comparator Level 3 threshold. If the comparator input is below L3_TRP, the comparator trips and the
backlight enters Level 3 (dark) mode. The following lists the code settings for photosensor current:
00000000 = 0 μA
00000001 = 0.54 μA
00000010 = 1.08 μA
00000011 = 1.62 μA

Description
Comparator Level 3 hysteresis. If the comparator input is above L3_TRP + L3_HYS, the comparator trips
and the backlight enters Level 2 (office) mode. The following lists the code settings for photosensor
current hysteresis:
00000000 = 0 μA
00000001 = 0.54 μA
00000010 = 1.08 μA
00000011 = 1.62 μA

Description
Lower eight bits of the 13-bit conversion value for the first light sensor (Bit 7 to Bit 0). The value is
updated every 80 ms (when the light sensor is enabled). This is a read-only register.
