Abstract:
A device for detecting high-level errors with an integrated self-check on an integrated circuit comprising a serial link control function for constituting an input-output port (109) between a parallel bus (L2CB, C2LB) and a serial link, said integrated circuit including a serializer circuit (109.sub.T) on output and a deserializer circuit (109.sub.R) on input, the invention comprising an insertion buffer (I-sb) having an output connected to one input of a two input exclusive OR operation, a second input of the exclusive OR operation adapted to receive a piece of information to be transmitted (o-s) in order to constitute, with insertion information issuing from the insertion buffer, a substitute information, and an additional buffer (I-tb) for comparing a first sequence corresponding to the information to be transmitted to the second input of the exclusive OR operation with a second sequence (tc) stored in the additional buffer (I-tb) in order to enable the transmission of the substitute sequence.
