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
judgement of the result, must be executed in the on-chip RAM. The on-chip program that is to be
downloaded is all in the on-chip RAM. Note that area in the on-chip RAM must be controlled so
that these parts do not overlap.
Figure 17.69 shows the program area to be downloaded.
