Electronic device intended to be connected in parallel on a bus line and able to receive and/or to send out data, this electronic device comprising interface logic arranged between the said bus line and the means of utilisation 3, in order to provide for transit and processing of the said data. According to the invention, this device is characterised in that the said interface logic 2 consists of a first, purely logic part 121, of a second part 13, 14 formed by microprogramming means with automatic running in which, except insofar as the first operation is concerned, the addresses corresponding to the various operations to be carried out are incomplete and of a third part 122 formed by a selector whose output signal corresponds to the address complement of the operation following that under way. <IMAGE>
