Brightness Register
[BRIGHT4–BRIGHT0] (POR = 0b10111)
The 5-bit brightness register corresponds with the 5-bit
brightness code used in the dimming control (see
Dimming Range
). BRIGHT4
–
BRIGHT0 = 0b00000 sets
minimum brightness, and BRIGHT4
–
BRIGHT0 =
0b11111 sets maximum brightness. The SMBus inter-
face does not control whether the device regulates the
current by analog dimming, DPWM dimming, or both;
this is done by MINDAC (Table 2).
Shutdown-Mode Register
[SHMD2–SHMD0] (POR = 0b001)
The 3-bit shutdown-mode register configures the oper-
ation of the device when the
SH
/SUS pin is toggled as
described in Table 7. The shutdown-mode register can
also be used to shut off directly the CCFL, regardless
of the
SH
/SUS state (Table 8).
