Abstract
A large multimaster IC bus system is partitioned into smaller bus segments. The bus segments are connected by bridges that isolate the segments and direct selected transactions and commands between the segments. The bridge may handle bus segment error conditions and particularly a hang on the Port B bus by attempting to cause any device on the bus segment to respond after the bus bridge has attempted to acquire the segment for a first predetermined period of time. If the bus responds within the first predetermined period of time, the bus bridge resets the bus segment.
