TSL2591 − Register Description

The Interrupt persistence filter sets the number of consecutive

out-of-range ALS cycles necessary to generate an interrupt.

Out-of-range is determined by comparing C0DATA (0x14 and

0x15) to the interrupt threshold registers (0x04 - 0x07). Note

that the no-persist ALS interrupt is not affected by the interrupt

persistence filter. Upon power up, the interrupt persistence

filter register resets to 0x00.
