Section 17 ROM
vector is read from is undetermined. Perform MAT switching in accordance with the description
in section 17.27, Switching between User MAT and User Boot MAT.
Except for MAT switching, the programming procedure is the same as that in user program mode.
The area that can be executed in the steps of the user procedure program (on-chip RAM, user
MAT, and external space) is shown in section 17.29.3, Procedure Program and Storable Area for
Programming Data.
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 17.74 shows the procedure for erasing the user MAT in user boot mode.
