TSL2672 − Principles O f Operation

Interrupt Persistence Filter Register (0x0C)

The interrupt persistence filter sets the number of consecutive

proximity cycles that are out-of-range before an interrupt is

generated. Out-of-range is determined by the proximity

interrupt threshold registers (0x08 through 0x0B). See

Interrupts in the Principles Of Operation section for further

information. Upon power up, the interrupt persistence filter

end of each proximity cycle.
