TSL2771 − Register Set

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. Separate filtering is provided for

proximity and ALS functions. ALS interrupts are generated

using C0DATA.
