<p>The invention relates to data source systems including digital circuits such as processors or control units in which a number of data lines are controlled in dependence of the position of a counter. A data source circuit of the system allows for several data lines to be simultaneously controlled by means of a comparison register and a comparator in that a given logic state is stored in a qualification unit, said logic state controlling the data lines when the counter position is reached ( via an output register). This offers the advantage that several components, for example the bus connection means of a processor, become independent of the control of these data lines and hence remain available for other functions.</p> |
