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 25.11,
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.
