AZ_CONFIG Register (Address 0xD6)

The following register configures how often the spectral engine offsets are reset (auto zero) to

compensate for changes of the device temperature. The typical time auto zero needs to be completed

is 15ms.

AUTOZERO FREQUENCY.

Sets the frequency at which the device performs auto

zero of the spectral engines.

Note: If FD

EN = “1” auto zero is also done for ADC 5.

The flicker detection measurement will be interrupted

and restarted in this case.
