SERIAL LINK COMMUNICATIONS PROTOCOL

摘要

An optimized method of bus contention comprising monitoring the bus for an idle or busy bus condition and either attempting an asynchronous bus access if the bus is idle or synchronously attempting a prioritized retry after a busy bus condition is sensed, after a bus access collision is sensed, and upon initial power-up, synchronized to the current message completion. The prioritization comprises a constant time delay plus a bit-time delay proportional to said accessing device's address identification.
