A method includes receiving a first address over an address bus at a first module, modifying the first address to generate a second address, and transmitting the second address over the address bus to a second module. The method also includes determining at the first module if at least one of the first and second addresses has a specified value. Modifying the first address could include incrementing or decrementing the first address to generate the second address. Determining if at least one of the first and second addresses has the specified value could include determining if the first address has a value of zero or a value of 2n−1 (where n is a specified number of bits in the address bus). Each module by design may be inserted into any position in a stack relative to a controller and be positionally selected without manual configuration of that module's address. |
