(1) On-chip RAM Address Map when Programming/Erasing is Executed
Some of the procedure programs that should be created by the user, such as a download request,
programming/erasing procedure, and determination of the result, must be executed in the on-chip
RAM. The on-chip programs to be downloaded are all in the on-chip RAM. Note that area in the
on-chip RAM must be controlled so that these programs do not overlap.
Figure 20.10 shows the program area to be downloaded.
