24.5
Programming/Erasing
Interface
754 Description amended
The procedure program for user program mode/user boot
mode is made by the user. Figure 24.5 shows the procedure
for creating the procedure program. For details, see section
24.8.2, User Program Mode, section 24.8.3, User Boot Mode.

MAT Select
The user MAT is selected when a value other than H'AA
is written, and the user boot MAT is selected when H'AA
is written. The MAT is switched by writing a value in
FMATS. To switch the MAT, make sure to follow section
24.10, Switching between User MAT and User Boot
MAT. (The user boot MAT cannot be programmed in
user program mode even if the user boot MAT is
selected by FMATS. The user boot MAT must be
programmed in boot mode or programmer mode.)
H'AA: User boot MAT is selected (user MAT is selected
when the value of these bits is other than H'AA).
Initial value when initiated in user boot mode.
H'00: Initial value when initiated in a mode other than
user boot mode (user MAT is selected).
[Programmable condition]
Execution state in the on-chip RAM
Note added
Notes: *1 The value is 1 in user boot mode and 0 otherwise.
24.8.4 Storable Areas
for On-Chip Program
and Program Data
793 Description amended
• In an operating mode in which the external address space is
not accessible, such as single-chip mode, the required
procedure programs should be transferred to the on-chip
RAM before programming/erasing starts (download result is
determined).
• The flash memory is not accessible during
programming/erasing. Programming/erasing is executed by
the program downloaded to the on-chip RAM. Therefore, the
procedure program that initiates operation should be
stored in the on-chip RAM other than the flash memory.
