9.7.1. Overview
The measurement engine manages the configuration register sets and controls registers contents.
Based on these parameters it configures the ZoomingADC™, supervises post processing of the measurements, stores the
results and flags the READY signal.
Once enabled the configuration 1 will be applied to the ZoomingADC™ and measurement will be done until the configuration
is disabled using the disable command.
