Sub Backlight Current Control Register (02h)

This register is used to set the currents for the backlight

current sinks assigned to the Sub Backlight Group. This

group can also be used to control green LEDs for limited

RGB control. These current sinks need to be enabled in the

Backlight Enable Control register to be active.

Bit D5

This bit is unused and is always a zero, so the maximum

pulse count for this register is 3.

SBL4 — SBL0 [D4:D0]

These bits are used to set the current for the sub backlight

current sinks. All enabled sub backlight current sinks will

sink the same current, as shown in Table 5.
