Section 20 Flash Memory
(1)
Parts of the procedure program that are made by the user, like download request,
programming/erasing procedure, and determination 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 20.10 shows the program area to be downloaded.
