Abstract
A wait signal formed by a program wait circuit incorporated in a microprocessor is transmitted to outside circuitry, such as a slave microprocessor or a direct memory access control device. Thereby an outside device assumes the functions of bus master which is incorporated into a wait operation for access to a memory unit. With such a construction, a microcomputer system comprising a plurality of devices to be made into a bus mask can be simplified.
