<p>PROBLEM TO BE SOLVED: To perform the communication with an external peripheral device in an optional step of a program and in a product state of an electronic equipment and to easily check the operation of a product of the electronic equipment and also to easily control the product. SOLUTION: The interrupt processing is carried out when the address data stored in an EROM are coincident with the output contents of a program counter. In this interrupt processing, an adjusting program is executed when the value of a code part is '1' in a program data area of the EROM. The adjusting program performs the communication with an adjuster. The communication data used for the communication include an adjustment code part, an address part and a data part. According to the value of the adjustment code part, the address subroutine of an address/data part are called, the data on the address part are written into the address of the address/data part, the address data on the address/data part are sent to the adjuster and the jumping is carried out to the address of the address/data part.</p> |
