Abstract

A method and a circuit configuration for operation of a bus system. A bus includes a bus control unit which controls only an arbitration and when time is exceeded during a data transmission. An actual data transmission is determined in a respective active master unit and an addressed slave unit. A characteristic of a bus cycle, such as a data length, access to a data area or a control area and a waiting cycle, is transmitted in encoded form through a multiplicity of control lines.
