Figure 25.17 shows the procedure for erasing the user MAT 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 25.17. For erasing the user MAT in user boot mode,
additional processing made by setting FMATS is required: switching from the user boot MAT to
the user MAT, and switching back to the user boot MAT after erasing completes.
User MAT Erasing in User Boot Mode
Note:
The MAT must be switched by FMATS to perform the erasing error processing in the user boot MAT.
