Register and Bit Definitions (continued)

BL[4:0]

These bits are used to set the current for the backlight

current sinks. All enabled backlight current sinks will sink

the same current, as shown in Table 1.

Table 1 — Backlight Current Control Bits

BL Enable Control Register (0x01)

This register is

used to enable the backlight current

sinks.

BLEN[4:1]

These bits are used to enable current sinks (active high,

default low).

BLEN_4 — Enable bit for backlight BL4

BLEN_3 — Enable bit for backlight BL3

BLEN_2 — Enable bit for backlight BL2

BLEN_1 — Enable bit for backlight BL1

When enabled, the current sinks will carry the current set

by the backlight current control bits BL[4:0], as shown in

Table 1.

Flash/Spotlight Control Register (0x02)

This register is used to configure the flash time-out feature,

the flash or spotlight current, and select flash or spotlight

current ranges.

FLTO

This bit is used to enable the flash safety time-out feature.

The default state is enabled with FLTO = 1. If this bit is set,

the device will turn off the flash after a nominal period of

1s. Two ways to re-enable the flash function after a safety

time-out are:

Pull the FLEN pin low to re-enable the flash

function

Clear and re-write FL[2:0]

FL[2:0]

These bits are used to set the current for the flash current

sink when configured for flash or spotlight by the FL/SPLB

bit. Bits FL[2:0] set the flash or spotlight current, as shown

in Table 2.
