Figure 25.16 shows the procedure for programming the user MAT in user boot mode.
The difference between the programming procedures in user program mode and user boot mode is
the memory MAT switching as shown in figure 25.16. For programming 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 programming
completes.
Note: The MAT must be switched by FMATS to perform the programming error processing in the user boot MAT.
