This register controls the interrupt filtering capabilities of the
device. Configurable filtering is provided to allow interrupts to
be generated after either an ALS integration cycle or if the
integration cycle has produced a result that is outside of the
values specified by threshold register for some specified
number of times.
ALS interrupts are generated by looking only at the ADC
integration results of Channel 0 photodiode.
