25.5 ROM Correction Application
How to apply the example shown in 25.4 is described below.
(1) Store the correction address and instruction after correction (patch program) to nonvolatile memory (such as
EEPROM
When two places should be corrected, store the branch destination judgment program as well. The branch
destination judgment program checks which one of the addresses set to correction address registers 0 and 1
(CORAD0 or CORAD1) generates the correction branch.
