Abstract

Data communication between a processing unit (UT) and external means may take place via a plurality of data streams (FXE1, FXE2, FXS1, FXS2). Means (GESi) check the mutual consistency of said streams and report and correct abnormalities. This self-synchronisation is achieved by inserting separators into the data streams to separate the data, and by means of a freezing mechanism (GL, FC) for freezing the internal operation of the processing unit.
