Default
Description
0
EN_BL
R/W
0
The grouped backlight enable signal.
0 = disable the grouped backlight.
1 = enable the grouped backlight.

Description
7
BST_MODE
R/W
0
This bit sets the boost regulator operation mode.
0 = LED operation mode.
1 = boost standalone operation mode.
6
BST_BL
R/W
0
This bit configures the boost regulator to provide the bias voltage to
all active LED channels or only to the active LED backlight channels.
(effective only when the boost regulator is configured in LED
operation mode).
0 = set the boost regulator to provide the bias voltage for all active
LED channels. In this configuration, the boost regulator provides the
adaptive headroom regulation according to all active LED current
sources.
1 = set the boost regulator to provide the bias voltage only to the
active LED backlight channels.
5
FOVR
R/W
0
This bit configures the override feature in the backlight fade in and
fade out.
0 = the fade in and fade out override is disabled.
1 = the fade in and fade out override is enabled.
4
Not used
R
Not used.
[3:2]
BST_OVP
R/W
00
This bit sets the overvoltage threshold in the boost output voltage in
VOUT4 pin.
00 = 18.5 V.
01 = 15 V.
10 = 10 V.
11 = 5.6 V.
1
Not used
R
Not used.
0
BST_IPK
R/W
0
This bit sets the peak current limit for boost regulator.
0 = 600 mA peak current limit.
1 = 300 mA peak current limit.

IBL[5:0]
R/W
000000
These bits set the LED current setting for the grouped backlight
(LED1). All grouped backlight LED channels follow this current
setting. A square law algorithm for 64 levels is used.
000000 = 0 mA.
000001 = 0.005 mA.
000010 = 0.020 mA.
…
111101 = 18.750 mA.
111110 = 19.370 mA.
111111 = 20 mA.
