Arrangement for detecting defects during the asynchronous transfer of digital measured values

摘要

An arrangement for detecting defects during the asynchronous transfer of digital measured values in a microcomputer system including an input circuit for producing the digital measured values. A storage register temporarily stores the digital measured values received from the input circuit. A multiplexer transmits the stored digital measured values to a microcomputer for further processing. The stored digital measured values are consecutively transmitted twice so that the microcomputer performs a comparison of both of the digital measured values. If both of the digital measured values are the same, the microcomputer processes the digital measured values. If the digital measured values are different, the multiplexer repeats the double transmission of the digital measured values.
