By changing the on-chip RAM address of the download destination in FTDAR, the erasing
program and programming program can be downloaded to separate on-chip RAM areas.
Figure 20.13 shows a repeating procedure of erasing and programming.
In the above procedure, download and initialization are performed only once at the beginning.
In this kind of operation, note the following:
• Be careful not to damage on-chip RAM with overlapped settings.
• Be sure to initialize both the erasing program and programming program.
In addition to the erasing program area and programming program area, areas for the user
procedure programs, work area, and stack area are reserved in on-chip RAM. Do not make
settings that will overwrite data in these areas.
Initialization by setting the FPEFEQ parameter must be performed for both the erasing
program and the programming program. Initialization must be executed for both entry
addresses: (download start address for erasing program) + 32 bytes and (download start
address for programming program) + 32 bytes.
