Abstract:
A method of operating a bus system, wherein the bus system has at least one primary unit, at least one secondary unit, at least one bus control unit, and a bus between the at least one primary unit and the at least one secondary unit, the bus having at least one address bus, at least one data bus and at least one control line, the method which comprises:defining a first data transmission configuration between the at least one primary unit and the at least one secondary unit, splitting a data transmission into a request data transfer and a response data transfer in the first data transmission configuration, and clearing the bus for data transmissions of other primary units and secondary units in a time between the request data transfer and the response data transfer;defining a second data transmission configuration between the at least one primary unit and the at least one secondary unit, blocking the bus between the request data transfer and the response data transfer in the second data transmission configuration; and controlling a data transmission between the at least one primary unit and the at least one secondary unit, addressed by the at least one primary unit, by selectively transmitting data in the first and second data transmission configurations.
