1. A circuit arrangement comprising two microcomputers which are connected to one another via a bus-coupler which includes a buffer store, where the data which is transmitted or is to be transmitted by means of the telegrams can be exchanged via the bus-couplet between the first microcomputer (1) which serves to generate and analyse remote control telegrams and the other microcomputer (2) which serves in particular for data processing, and where the microcomputer (1) which serves to generate and analyse remote control telegrams is provided with a peripheral module (21) for the serial transmission of the remote control telegrams, characterized in that the other microcomputer (2) which serves for data storage and/or data processing is connected to a peripheral module (22) for serial input or output of data, and that the buffer store of he bus coupler is provided with at least one data register for each direction of transmission, and that the microcomputer (1) which serves to generate and analyse remote control telegrams determines the time of a word-serial data exchange via the buffer store both in the one direction of transmission and in the other direction of transmission, where the bit sequence of the bit-serial transmission of the data which takes place in the peripheral modules (21, 22) is contrived to be such that the duration of a serial data word in the bit-serial transmission is longer than the duration of the word-serial data exchange between the microcomputer (1, 2). |
