20.6.2
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 prepare on-
board means for controlling FWE, on-board means of supplying programming data, and branching
conditions. 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, as in boot mode. Figure 20.7 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 20.8, Flash Memory Programming/Erasing.
