9.6.2.4 Completion of Synchronization

In order to check if synchronization is complete, the user can either poll the relevant bits in SYNCBUSY or use the Synchronization Ready interrupt (if available). The Synchronization Ready interrupt flag will be set when all ongoing synchronizations are complete, i.e. when all bits in SYNCBUSY are '0'.

Note: The Synchronization Ready interrupt (if available) cannot be used for Enable and Software Reset write-synchronization.
