Description
Proximity Valid. Indicates that the proximity state has completed a
cycle since either an assertion of PEN or the last readout of PDATA.
ALS Valid. Indicates that the ALS state has completed a cycle since
either an assertion of AEN or the last readout of at least one the
CDATAL register.
Reserved.
ALS Digital Saturation. Indicates that the maximum counter value
has been reached. Maximum counter value depends on integration
time set in the ATIME register.
ALS Analog Saturation. Indicates that the intensity of ambient
light has exceeded the maximum integration level for the ALS
analog circuit.
Proximity ADC Saturation. Indicates that the maximum ADC value
has occurred.
Proximity Reflective Saturation. Indicates that the intensity of
reflected light has exceeded the maximum integration level for the
proximity analog circuit.
Proximity Ambient Saturation. Indicates that the intensity of
ambient light has exceeded the maximum integration level for the
proximity analog circuit.
