The subsystem integrated from a semiconductor chip (B) includes at least one register (MR) which can be used for the internal operating sequence and into which a register information consisting of a number of bits is entered which is variable as determined by a further information received as pulse series. The further information is in each case supplied by a single-pin chip terminal (H). It is converted by a counting circuit (ZM) into a register information which has an effect in the subunit (B) itself. The chip (B) is reset into the initial state for the operating sequence, and the incoming further information is also converted, by an externally supplied resetting signal via a resetting input (R). Whilst the resetting signal is lacking, the single-pin chip terminal (H) can be used for supplying control pulses which trigger other pulses in the chip (B). During the switching-over of the chip (B), the counting mode of an input counter (EZ) and of an output counter (AZ) for an associated buffer memory (QS) can be switched over. An associated program controller can also be switched over in order to produce various types of stopping of the program sequence. The method has the advantage of being able to transmit different types of information via a single chip terminal. <IMAGE> |
