<p><P>PROBLEM TO BE SOLVED: To provide a microprocessor equipped with a data transfer engine for enabling a processor core to automatically perform data transfer to be performed the next without performing the polling of the end of the processing of a peripheral circuit. <P>SOLUTION: A data transfer engine is provided with a processing status register, and the processing status register is provided with bits which are made rewritable by a peripheral circuit, and assigned to each peripheral circuit when data processing ends. This data transfer engine monitors the value of the processing status register instead of a processor core, and starts itself when all the processing ends, and starts the assigned data transfer. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
