Abstract
PURPOSE: To reduce the number of ROMs to be replaced to a minimum by rewriting control program data stored in RAM according to corrected data stored in ROM corresponding to a loader program.
CONSTITUTION: Right after the system is powered ON, CPU2 transfers a control program stored in ROM3 to RAM4 by a loader program stored in ROM1 and then rewrites control program data stored in RAM4 according to corrected data stored in ROM5 corresponding to the loader program. On detecting the end of the corrected data, CPU2 shifts from control by the loader program to that by the control program. Thus, one data block is formed of a corrected memory address and corrected data, so that the number of ROMS to be replaced will be reduced.
