7
ALS Saturation. If ASIEN is set, indicates ALS saturation. Check the STATUS2 register
to differentiate between analog or digital saturation.
Proximity Saturation. If PGSIEN is set, indicates analog saturation during a previous
6 proximity cycle. Check the STATUS2 register to differentiate between ambient or
reflected light saturation.
Proximity Interrupt. If PIEN is set, indicates that a proximity detect or release event
5 that met the programmed proximity thresholds (PILT or PIHT) and persistence (PPERS)
occurred.
4
ALS Interrupt. If ASIEN is set, indicates that an ALS event that met the programmed
ALS thresholds (AILT or AIHT) and persistence (APERS) occurred.
IRBeam Interrupt. If IIEN is set, indicates that the device is asserting an
3 end-of-transmission interrupt after transmitting a block of data. Bit is mirrored in the
ISTATUS register.
2 Reserved.
Calibration Interrupt. Indicates that either calibration is finished or that one of
certain events have occurred during normal operation. If each function is enabled,
1 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).
0 Reserved.
