FD_PERS

Flicker Detect Persistence.

Sets the number of consecutive flicker detect results

that must be different before the flicker detect status

will be changed. Flicker detection interrupts on SINT

are affected by this setting. Flicker detect

persistence is equal to

2(��_��−1)

Setting “0” equals to every time.

AZ_CONFIG Register (Address 0xDE)

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 15 ms.

AZ_NTH_ITERATION

255

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.
