<p>PROBLEM TO BE SOLVED: To shorten the data transfer time with no addition of handware by transferring the compressed data attached to a program from a PROM writer. SOLUTION: The data transfer time is shortened by executing a step S11 where a boot program is started, a step S12 where a control program including communications, writing and depressing program is transferred from a PROM writer to a RAM built into a microcomputer, a step S13 where the control program is received and the control is shifted to the control program from the boot program, a step S14 where the data 102 compressed by the PROM writer are transferred to the RAM, a step S15 where the compressed data 102 of the RAM are depressed by the depressing program, a step S16 where the depressed data 102 are written into an EPROM built into the microcomputer and a step S17 where the steps S14-16 are repeated until the processing of the data 102 stored in the RAM are over.</p> |
