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.
