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 ADC integration cycle or if the ADC integration has
produced a result that is outside of the values specified by threshold register for some specified amount of time.
