ALS_THRESHOLD_

CHANNEL

0R/W

Selects the modulator channel used for the ALS threshold

metering and subsequent interrupt.

001b: Modulator 1

010b: Modulator 2

011b: Modulator 3

APERS

R/W

ALS Interrupt Persistence. Defines a filter for the

number of consecutive occurrences that ALS

measurement data must remain outside the threshold

range between AILT and AIHT before an interrupt is

generated. The ALS data channel used for the persistence

filter is set by ALS_THRESHOLD_CHANNEL. Any sample

that is inside the threshold range resets the counter to 0.

Interrupts are generated at

0x0: Every ALS cycle

0x1: Any ALS value outside the threshold range

0x2: 2 consecutive ALS values outside the range

0x3: 3 consecutive ALS values outside the range

0x4: 5 …

0x5: 10 …

…… continued in increments of 5 values

0xE: 55 …

0xF: 60 consecutive ALS values outside the range
