7. It is necessary to execute additional programming processing during the course of the
H8/3062F-ZTAT A-mask version program/program-verify procedure. However, once 128-
byte-unit programming is finished, additional programming should not be carried out on the
same address area. When executing reprogramming, an erase must be executed first. Note that
normal operation of reads, etc., is not guaranteed if additional programming is performed on
addresses for which a program/program-verify operation has finished.
