LS Measurement Rate

Bit[6:4]

Light Sensor Resolution/ Bit Width. The resolution selected via this register will have an effect on the

measurement time and the accuracy of the measurement.

20-Bit – 400ms

19-Bit – 200ms

18-Bit – 100ms (default)

17-Bit – 50ms

Bit[2:0]

LS Measurement Rate. This bit field controls the timing of the periodic measurements of the light

sensor in Active Mode.

Note:

When the measurement repeat rate is programmed to be faster than possible for the specified

ADC measurement time, the repeat rate will be lower than programmed (maximum speed).

Writing to this register stops the ongoing measurements and starts new measurements (depending on the respective enable bits).
