ABSTRACT:
An interface controller for an addressable interface module. The interface module is for coupling along with other addressable interface modules over a communication bus to a central processor. Each interface module responds to a unique base address, unique to such interface module provided by the central processor on the communication bus, responsive either to a read command for reading data from such interface module to the communication bus or to a write command for writing data from the communication bus to such interface module. A stored configuration base address is provided in the interface controller for use in determining the unique address for which the corresponding interface module is to respond. A decoder in the interface controller decodes the base address including a modified configuration address for use by the corresponding interface module in determining the unique address for response by the corresponding interface module. The stored configuration base address is automatically modified in the event the base address is the same as the unique base address for one of the other interface modules. In this regard, the means is responsive to a predetermined address on the communication bus and a read command for modifying the stored configuration base address to such modified configuration address.
