Description

ASAT

ALS Saturation. When asserted, the analog sensor was at the upper

end of its dynamic range. The bit can be de-asserted by sending a clear

channel interrupt command (0xE6 CICLEAR) or by disabling the ALS

ADC (AEN=0). ATIME and AGAIN are controls that can be adjusted to set

when saturation happens. This bit triggers an interrupt if ASIEN in AUX

is set.

Reserved

Reserved.

AINT

ALS Interrupt. If AEN is set, indicates that an ALS event that met the

programmed ALS thresholds (AILT or AIHT) and persistence (APERS)

occurred.

Reserved

3:1

Reserved.

AVALID

RGBC Valid. Indicates that the RGBC cycle has completed since AEN

was asserted.
