Circuit arrangement for exchange of data between two microcomputers

摘要

In a circuit arrangement for exchange of data between two microcomputers, preferably between two microcomputers which are operated in parallel for security reasons, an interface circuit is assigned to each of the two microcomputers, and includes a transmitter and a receiver, each having a read-write memory. The two interface circuits are connected to each other by a clock line and one serial data line for each direction, and provided with circuits to control the transmission and receiving process. <IMAGE>
