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 2.
