A data processing system for accessing an external device and method therefor

摘要

A data processor (10) flexibly interfaces with both a variety of memory devices and external peripheral devices. A control register (94) is provided for dynamically controlling a data bus configuration of the data processor. A set of bits (DSZ) in the control register (94) provides configuration control which indicates a width of data communicated with the data processor and a configuration of the integrated circuit terminals (124) by which the information is communicated. <IMAGE>
