While the SWE1 bit is set to 1 to perform programming or erasing for the addresses H'000000 to
H'03FFFF, this address area cannot be read. While the SWE2 bit is set to 1 to perform
programming or erasing for the addresses H'040000 to H'07FFFF, this address area cannot be
read. The control program that performs programming and erasing should be run in on-chip RAM
or flash memory except for the above address areas. When the program is located in external
memory, an instruction for programming the flash memory and the following instruction should
be located in on-chip RAM.
Figure 17.44 shows the procedure for executing the program/erase control program when
transferred to on-chip RAM.
Note: The watchdog timer should be activated to prevent overprogramming or overerasing
due to program runaway, etc.
