Abstract

Microprocessors commonly have an 8-bit data bus and a 16-bit address bus. When a storage device of the type which requires regeneration to preserve its data is connected to such a microprocessor, conflicts can arise between access by the microprocessor and the regeneration circuitry since the regeneration cycle takes the place of the normal read or write operations. At some point in the storage cycle a decision must be made as to whether the microprocessor requires access to this storage and whether it should take priority over storage regeneration.
