An interface structure and protocol is provided that meets the following objectives: 1. Narrow (few lines) = low cost implementation 2. Simple (straightforward protocols) = low cost implementation 3. Asynchronous operation = one side of the interface can disconnect to execute a long time internal operation not requiring the interface, thus freeing the interface for other usages, end then re-connect when appropriate. 4. Parallel (with parity), bidirectional data transfuser equals high transmission rate with error checking.
