An N-bit word is produced from an M-bit code received on an M-bit line, M being larger than N, the M-bit code comprising at least an M-bit code word and a previous M-bit code word, the M-bit code word comprising different levels at at least two bit positions, and the previous M-bit code word comprising levels opposite to the different levels at the corresponding bit positions, by comparing the levels at the two bit positions of the M-bit code word to obtain a first value, comparing the levels at the two corresponding bit positions of the previous M-bit code word to obtain a second value, detecting that the first value is opposite to the second value, and decoding the M-bit code word responsive to detecting that the first value is opposite to the second value. An advantage of the present invention is that all the lines taking part in the transmission have the same electrical characteristics, the same meaning and the same kind of loads.
