Parts of the procedure program that is made by the user, like download request,
programming/erasing procedure, and decision of the result, must be executed in the on-chip RAM.
Since the on-chip program to be downloaded is embedded in the on-chip RAM, make sure the on-
chip program and procedure program do not overlap. Figure 20.12 shows the area of the on-chip
program to be downloaded.
