Persistence Register (0x0C)

The persistence register controls the filter interrupt capabilities

of the device. Configurable filtering is provided to allow

interrupts to be generated after every ADC cycle or if the ADC

cycle has produced a result that is outside of the values

specified by threshold register for some specified amount of

time. ALS interrupts are generated using C0DATA.
