Section 21 Flash Memory (0.18-μm F-ZTAT Version)
MAT is being programmed. Because the user boot MAT is hidden while the user MAT is being
programmed, the procedure program must be located in an area other than flash memory. After
programming completes, switch the MATs again to return to the first state.
MAT switching is enabled by writing a specific value to FMATS. However note that while the
MATs are being switched, the LSI is in an unstable state, e.g. access to a MAT is not allowed until
MAT switching is completed, and if an interrupt occurs, from which MAT the interrupt vector is
read is undetermined. Perform MAT switching in accordance with the description in section 21.6,
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 21.4.4, 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 processing 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 21.14 shows the procedure for erasing the user MAT in user boot mode.
