Description
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.
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.
RGBC Valid. Indicates that the RGBC cycle has completed since AEN
was asserted.
