Abstract
Microcomputers are typically designed having a cycle time during which peripheral devices are accessed. This cycle is subdivided such that during a device access certain signals sequentially are activated to control the flow of data to or from the device over a set of special purpose leads. There is disclosed an arrangement for use when the device cannot respond within the allotted cycle for controlling the device access so that multiple successive cycles are used for a single device access. In this manner the microcomputer's speed is independent from the device response speed.
