19.6.2
On-board programming/erasing of an individual flash memory block can also be performed in user
program mode by branching to a user program/erase control program. The user must set branching
conditions and provide on-board means of supplying programming data. The flash memory must
contain the user program/erase control program or a program that provides the user program/erase
control program from external memory. As the flash memory itself cannot be read during
programming/erasing, transfer the user program/erase control program to on-chip RAM or
external memory. Figure 19.6 shows a sample procedure for programming/erasing in user program
mode. Prepare a user program/erase control program in accordance with the description in section
19.8, Flash Memory Programming/Erasing.

while a low level is being applied to the FWP pin, activate the watchdog timer in case of handling CPU
runaways.
