DETAILED REGISTER DESCRIPTIONS
Table 7. Register 0x00, Device Mode and Status (MODE_STATUS)
Bit
7
Name
STNBY
R/W
R/W
Description
0 = the device is in standby mode. (If 1.8V ≤ VDDIO ≤ 2.7V, then I 2 C.)
1 = the device is in operating mode. Additional functions such as backlight driver, LED sinks, and
ambient light sensor functions can be enabled.
6
BL_EN
R/W
0 = the backlight driver is disabled.
1 = the backlight driver is enabled.
5
DIM_EN
R/W
0 = dim mode is disabled.
1 = dim mode is enabled.
Dim mode can be enabled in two ways. One is by manually setting this bit, in which case, the
backlight stays at a dim level until this bit is manually cleared. The second method is by setting the
DIMT timer, in which case, an internal state machine sets this bit and clears it when the timer expires.
4 1
OVP_INT
R/W
0 = no overvoltage protection (OVP) condition.
1 = OVP condition detected.
Once set, this bit can be cleared by writing a 1 to it.
3 1
CMPR_INT
R/W
0 = no ambient light sensor comparators have triggered.
1 = one of the ambient light sensor comparators has triggered.
Once set, this bit can be cleared by writing a 1 to it.
2 to 0
Not used
1
If one of the interrupt bits is cleared and there is a pending interrupt, INT deasserts for 50 μs and reasserts, but the status of the pending interrupt stays set .
Table 8. Register 0x01, Interrupt Enable (INTERRUPT_ENABLE)
Bit
7 to 5
4
Name
Not used
AUTO_LD_EN
R/W
R/W
Description
0 = autoload is disabled.
1 = autoload is enabled. A 1 mA dummy load turns on when the backlight code is less than 8 (linear
law) or less than Code 32 (square law).
3
CMPR_IEN
R/W
0 = ambient light sensor comparator(s) interrupt is disabled.
1 = ambient light sensor comparator(s) interrupt is enabled.
2
OVP_IEN
R/W
0 = OVP interrupt is disabled.
1 = OVP interrupt is enabled.
1 to 0
Not used
Table 9. Register 0x02, Backlight Control (BL_CONTROL)
Bit
7 to 6
Name
BL_LVL
R/W
R/W
Description
Brightness level control for the backlight.
00 = daylight (L1).
01 = office (L2).
10 = dark (L3).
See the description for the BL_AUTO_ADJ bit.
5 to 4
BL_LAW
R/W
Backlight fade-on/fade-off transfer characteristic.
00 = linear.
01 = square.
10 = Cubic 1.
11 = Cubic 2.
