Each chip includes logic for recognizing a code, the logic being programmable by EEPROMs so that each chip can be set to recognize a unique address code. The modules can be connected to input or output devices, or both. All modules are interconnected by no more than four wires. A clock pulse source is connected to the system, the source being periodically interrupted to synchronize the system when the clock pulses restart. | |
