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 program. The user must set branching
conditions and provide on-board means of supplying programming data. The flash memory must
contain the program/erase program or a program which provides the program/erase program from
external memory. Because the flash memory itself cannot be read during programming/erasing,
transfer the program/erase program to on-chip RAM, as like in boot mode. Figure 20.6 shows a
sample procedure for programming/erasing in user program mode. Prepare a program/erase
program in accordance with the description in section 20.7, Flash Memory Programming/Erasing.
