7. It is necessary to execute additional programming processing during the course of the
H8S/2633 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.
