7. It is necessary to execute additional programming processing during the course of the
H8/3052BF 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.
