Section 23 ROM
23.7.2
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 which provides the user
program/erase control program from external memory. Because the flash memory itself cannot be
read during programming/erasing, transfer the user program/erase control program to on-chip
RAM, as like in boot mode. Figure 23.10 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 23.8, Flash Memory Programming/Erasing.
