read is undetermined. Perform MAT switching in accordance with the description in section 20.6,
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 20.4.4, Storable Area for Procedure Program and
Program Data.
(3) User MAT Erasing in User Boot Mode
For erasing the user MAT in user boot mode, additional processing made by setting FMATS is
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 20.15 shows the procedure for erasing the user MAT in user boot mode.
