Spectral Data and Status

The ASTATUS register provides saturation and gain status associated to each set of spectral data.

Reading the ASTATUS register (0x94) latches all 36 spectral data bytes to that status read. Reading

these bytes consecutively (0x94 to 0xB8) ensures that the data is concurrent. All spectral data are

stored as 16-bit values. If flicker detection is enabled, spectral channel five (CH5 ADC) is used for the

flicker detection function. The ASTATUS and spectral data registers are read only.
