SAMPLE_TIME[2:0]

011b

R/W

Flicker sampling time and ALS measurement time step.

Sets the time in steps of 1.388889μs modulator clock.

Please observe that SAMPLE_TIME needs to be set in

(2048 counts).

SAMPLE_TIME+1 = 1/FlickerSamplingFreq/1.388889μs

Default: 179+1 = 1/4000Hz / 1.388889μs

(180 counts as counted 0-179)

ALSMeasurementTimeStep = (SAMPLE_TIME+1) x

1.388889μs

Default: 250μs = (179+1) x 1.388889μs
