Description

ASAT

ALS Saturation. If ASIEN is set, indicates ALS saturation. Check the STATUS2 register

to differentiate between analog or digital saturation.

PGSAT

Proximity Saturation. If PGSIEN is set, indicates analog saturation during a previous

proximity cycle. Check the STATUS2 register to differentiate between ambient or

reflected light saturation.

PINT

Proximity Interrupt. If PIEN is set, indicates that a proximity detect or release event

that met the programmed proximity thresholds (PILT or PIHT) and persistence (PPERS)

occurred.

AINT

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

ALS thresholds (AILT or AIHT) and persistence (APERS) occurred.

IINT

IRBeam Interrupt. If IIEN is set, indicates that the device is asserting an

end-of-transmission interrupt after transmitting a block of data. Bit is mirrored in the

ISTATUS register.

Reserved

Reserved.

CINT

Calibration Interrupt. Indicates that either calibration is finished or that one of

certain events have occurred during normal operation. If each function is enabled,

CINT will be asserted if too many zeroes occur too often in a period of samples, if the

proximity baseline has decreased, or if at least one offset register has been adjusted.

Check the CALIBSTAT register to identify the triggering event(s).
