Description
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.)
