Section 18 Flash Memory (0.18-µm F-ZTAT Version)
(5)
FMATS selects the user MAT or user boot MAT. Writing to FMATS should be done when a
program in the on-chip RAM is being executed.
Note:
(6)
FTDAR specifies the start address of the on-chip RAM at which to download an on-chip program.
FTDAR must be set before setting the SCO bit in FCCS to 1.

Description
MAT Select
The memory MATs can be switched by writing a value
to FMATS.
When H'AA is written to FMATS, the user boot MAT is
selected. When a value other than H'AA is written, the
user MAT is selected. Switch the MATs following the
memory MAT switching procedure in section 18.11,
Switching between User MAT and User Boot MAT. The
user boot MAT cannot be selected by FMATS in user
programming mode. The user boot MAT can be
selected in boot mode or programmer mode.
H'AA: The user boot MAT is selected. (The user MAT is
H'00: The user MAT is selected.
