The Comparator need not be used for pure connectivity testing, since all analog inputs are
shared with a digital port pin as well.

configuration is considered fixed for a given application. The user is advised to scan the same
clock option as to be used in the final system. The enable signals are supported in the scan
chain because the system logic can disable clock options in sleep modes, thereby disconnect-
ing the Oscillator pins from the scan path if not provided.
