With active auto offset compensation the offset value is measured before each ambient light measurement
For technical questions, contact:
In order to compensate a technology, package or temperature related drift of the ambient light values
Bit values sets the number of single conversions done during one measurement cycle. Result is the
Number of conversions = 2
This function can be used for performing faster ambient light measurements. Please refer to the
