(1) On-Chip RAM Address Map when Programming/Erasing is Executed
Parts of the procedure program that are made by the user, like download request,
programming/erasing procedure, and decision of the result, must be executed in the on-chip
RAM. All of the on-chip program that is to be downloaded is in on-chip RAM. Note that on-
chip RAM must be controlled so that these parts do not overlap.
