DO_ALS_FINAL_

PROCESSING

0R/W

If this bit is set to “1” and flicker measurement takes

longer than ALS measurement, ALS measurement

writings are postponed until flicker measurement is

finished. Otherwise ALS data is not written to FIFO.

Bit Description

7AINT_DIRECT

R/W

ALS Interrupt Direct. Enables the direct mode of ALS

interrupt. ALS interrupts are only generated when

ALS_DATA (selected by ALS_THRESHOLD_CHANNEL)

moves over the hysteresis edges (AINT_AILT and

AINT_AIHT). If bit is “0”, interrupts are always

generated if ALS_DATA is above AIHT or below AILT.

The status of the ALS interrupt is directly output on

the INT or GPIO pin if this mode is enabled and either

of those pins are configured to do so according to

the INT_PINMAP and VSYNC_GPIO_PINMAP settings.
