MAT Select
These bits are in the user-MAT selection state when the
value other than H'AA is written and in the user-boot-
MAT selection state when H'AA is written. The MAT is
switched by writing the value to FMATS. When the MAT
is switched, follow section 20.6, Switching between User
MAT and User Boot MAT. (The user boot MAT cannot
be programmed in user program mode if user boot MAT
is selected by FMATS. The user boot MAT must be
programmed in boot mode or in programmer mode.)
