AB-66 Resolving Bus Contention When Interfacing the Intel386(TM) EX Embedded Processor with Intel Flash

Examining the worst-case timing relations for interfacing the Intel386(TM) EX embedded processor with flash indicates bus contention on a memory read followed by a memory write. However, the Intel386 EX embedded processor specification t50 resolves this issue and guarantees no bus contention if the flash data float time (tGHQZ) is <= t50. This document explains why there is no contention when interfacing with Intel Flash.
