Bit Name Bit No. Description

L2_TRP [7:0]

Comparator Level 2 threshold. If the comparator input is below L2_TRP, the comparator trips and the

backlight enters Level 2 (office) mode. The following lists the code settings for the photosensor current:

00000000 = 0 A

00000001 = 4.3 A

00000010 = 8.6 A

00000011 = 12.9 A

…

11111010 = 1080 A

…

11111111 = 1106 A

Although codes above 1111010 (250 decimal) are possible, they should not be used. Furthermore, the

maximum value of L2_TRP + L2_HYS must not exceed 11111010 (250).

L2_HYS [7:0]

Comparator Level 2 hysteresis. If the comparator input is above L2_TRP + L2_HYS, the comparator trips and

the backlight enters Level 1 (daylight) mode. The following lists the code settings for the photosensor

current hysteresis:
