Register and Bit Definitions (continued)

FL/SPLB

This bit is used to select either the flash or spotlight

current ranges. If this bit is set, the FL current sink can

be used to drive a flash of maximum duration 500ms and

the current range will be the high (flash) current range. If

this bit is cleared, the FL current sink can be used to drive

a continuous spotlight at a lower current and the current

range will be the lower (spotlight) current range, as shown

in Table 1.

LDO Control Register (0x03)

This register is used to enable the LDOs and to set their

output voltages.

LDO2[2:0]

These bits are used to set the output voltage of LDO2, as

shown in Table 2.
