7. It is necessary to execute additional programming processing during the course of the

H8/3028F-ZTAT 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.
