TCS3772 − Register Description

Persistence Filter Register (0x0C)

The PERSISTENCE FILTER 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 clear channel.
