7.5.3 Programming/Erasing in User Mode
On-board programming/erasing of individual flash memory blocks is also possible in user mode
by branching to the user programming/erasure-control program. The user must set the branching
conditions and provide the on-board means of supplying the programming data. The flash memory
must contain the user programming/ erasure-control program or a program that allows the user
programming/erasure-control program to be supplied externally. As the flash memory itself cannot
be read during programming/erasing, transfer the user programming/erasure-control program to
the on-chip RAM to execute, as in boot mode. Figure 7.12 shows a sample procedure for
programming/erasing in user mode. Prepare user programming/erasure-control program in
accordance with the description in section 7.6, Programming/Erasing.
