<p><P>PROBLEM TO BE SOLVED: To provide a controller capable of writing the operation program of a control circuit on board while suppressing an increase in circuit area and an increase in manufacturing cost. <P>SOLUTION: An ATA register 22a is connected to a host computer 30. When the command of a command code AOh is transmitted from the host computer to the ATA register 22a, data transmitted from the host computer is transmitted through the ATA register 22a to an ATAPI register 22b. A decoder 23 is connected to the ATAPI register 22b, a special command is transmitted through the ATA register 22a to the ATAPI register 22b, and the transmitted data (command and microcomputer control software) are decoded to generate an address and data for writing data in a flash ROM 12. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
