A peripheral processor may use the simplified asynchronous communication network for message transfer operation with a processor unit 10 (see Fig. 1) having a bus-oriented system. This bus-oriented system requires a unique interface to interface the processor unit's parallel data bus to the peripheral's serial asynchronous data communication channel. If the processor unit has other dedicated functions; then the interface must provide transmit and receive control as well as data formatting and buffering. This network uses minimal circuit hardware that provides efficient execution of processor code. (Image Omitted) A serial asynchronous communication channel (see Fig.
