Description

ASAT

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

to differentiate between analog or digital saturation.

PGSAT

Proximity/Gesture 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.

Reserved

Reserved.

GINT

Gesture Interrupt. If GIEN is set, indicates that one or more gesture event conditions

have been met. GINT indicates that there is data available in the FIFO buffer for

readout and GFIFO_LVL is greater than GFIFOTHR or that GVALID has become

asserted when GMODE transitioned to zero. The bit is reset whenever the FIFO buffer

is completely emptied (read).

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).
