R, SC
The Analog Saturation flag signals that the ALS results
may be unreliable due to saturation of the AFE.
The Proximity Saturation flag indicates that an ambient-
0
R, SC or reflective-saturation event occurred during a
previous proximity cycle.

PINT
The Proximity Interrupt flag indicates that proximity
0
R, SC results have exceeded thresholds and persistence
settings.

CINT
The ALS Interrupt flag indicates that ALS results
0
R, SC (photopic channel) have exceeded thresholds and
persistence settings.

The Calibration Interrupt flag indicates that calibration
has completed.

The Reflective Proximity Saturation Interrupt flag
signals that the AFE has saturated during the IR LED
active portion of proximity integration.
The Ambient Proximity Saturation Interrupt flag signals
that the AFE has saturated during the IR LED inactive
portion of proximity integration.

All flags in this register can be cleared by setting the bit high.
Alternatively, if the CFG3.int_read_clear bit is set, then simply
reading this register automatically clears all eight flags.
