ABSTRACT:
A data processing system (10) flexibly interfaces with both a variety of memory devices and external peripheral devices. A control register (94) is provided for dynamically controlling a timing relationship for read and write accesses executed by the system. A first set of bits (PA) in the control register provides timing control for an initial amount of time required to read a first data value from an external device. A second set of bits (SA) in the control register provides timing control for each successive amount of time required to read a successive data value from the external device.
