Abstract (en)
[origin: WO2006128810A2] The invention relates to a method for communication between at least two subscribers (2, 3) of a communication system via a plurality of data lines (D0 - D31) of a data bus, some of these data lines being used as address lines (A0 - A23) of an address bus and data and addresses being transmitted in multiplex transmission. In order to facilitate a simple and inexpensive protection of the transmission path between the subscribers (2, 3), redundant data are transmitted via at least one of the data lines (D24 - D31) that is not used as the address line (A0 - A23) at the same time the address is transmitted via the address line (A0 - A23). Checksums (so-called check bits) are preferably transmitted as the redundant data. The inventive method is preferably used for communication between a microprocessor (3) and an external memory module (2).
