(3) User MAT Erasing in User Boot Mode
For erasing the user MAT in user boot mode, additional processings made by setting FMATS
are required: switching from user-boot-MAT selection state to user-MAT selection state, and
switching back to user-boot-MAT selection state after erasing completes.
Figure 23.15 shows the procedure for erasing the user MAT in user boot mode.
