Abstract
A method for the control of an electronic circuit of the type includes at least one access pin to receive and/or deliver control signals, includes the generation, in a control unit, of control signals from data elements received serially through a data transfer input/output device. The method also includes the following steps: (1) extracting a control word included in the data received serially; and (2) decoding the control word extracted in the previous step in order to perform an operation, as a function of the value of the control word, thus modifying the logic state of at least one control signal. A control unit for accomplishing the foregoing steps includes a circuit for the extraction of a control word included in data elements received serially through a means for the serial transfer of data in the electronic circuit; a circuit for the decoding of said control word; and two or more of flip-flop circuits controlled by activation signals generated by the decoding circuit, the logic state of the output of the flip-flop circuits directly or indirectly determining the logic state of the control signals generated by the control unit.
