Section 23 Flash Memory
Except for memory MAT switching, the programming procedure is the same as that in user
program mode.
(3)
For erasing the user ROM in user boot mode, additional processing made by setting the FMMS bit
in FLMMATS is required: switching from the user boot ROM to the user ROM, and switching
back to the user boot ROM after erasing completes.
Figure 23.11 shows the procedure for erasing the user ROM in user boot mode.
The difference between the erasing procedures in user program mode and user boot mode is the
memory MAT switching, as shown in figure 23.11.
