| Zusammenfassung: | PROBLEM TO BE SOLVED: To update the program data of a flash memory without requiring largely-scaled update data capturing means or wire cable, and to surely and easily achieve an update operation. SOLUTION: Terminal equipment stores program data to be executed by a CPU 1 into the flash memory 2 and transfers the data to a work memory 3 to execute program processing. The terminal equipment is provided with a radio reception device 4 for receiving the program data from an external device by radio, and for directly writing the program data in the flash memory. This process includes writing the program data in the flash memory after temporarily writing the program data in the work memory. COPYRIGHT: (C)2008,JPO&INPIT |
