13. ROM CORRECTION
ROM correction is a function for avoiding execution of a part of a program in the internal ROM that needs to be
corrected by executing the corrected program, which is stored in the internal RAM.
By using this function, instruction bugs found in the internal ROM can be avoided and the program flow can be
changed.
Up to four combinations between source internal ROM (program) and target RAM sections are available for the
ROM correction.
