Persistence Register (0x0C)
The Persistence Register controls the filtering interrupt
capabilities of the device. Configurable filtering is provided to
allow interrupts to be generated after each integration cycle or
if the integration has produced a result that is outside of the
values specified by the threshold register for some specified
amount of time. Separate filtering is provided for proximity and
the RGBC clear channel.
