Bit Description

7Reserved

ALS_DATA_

VALID

ALS Data Valid. Indicates that the ALS state has completed a

cycle since either an assertion of AEN or the last readout of the

ALS_STATUS register.

5Reserved

ALS_DIGITAL_

SATURATION

ALS Digital Saturation. Indicates that a counter value has been

reached that cannot be expressed with the selected data

format defined with ALS_MSB_POSITION. Maximum counter

value also depends on integration time set in the ATIME

FD_DIGITAL_

SATURATION

Flicker Detect Digital Saturation. Indicates that the maximum

counter value has been reached during flicker detection.

2Reserved

MOD_

ANALOG_

SATURATION1

ALS Analog Saturation of Modulator1. Indicates that the

intensity of ambient light has exceeded the maximum

integration level for the ALS analog circuit.

MOD_

ANALOG_

SATURATION0

ALS Analog Saturation of Modulator0. Indicates that the

intensity of ambient light has exceeded the maximum

integration level for the ALS analog circuit.
