• Be careful not to damage on-chip RAM with overlapped settings.
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.
• Be sure to initialize both the erasing program and programming program.
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.
