Section 17 ROM
(5) Flash MAT Select Register (FMATS)
FMATS specifies whether user MAT or user boot MAT is selected.
Bits 7 to 0—MAT Select (MS7 to MS0): These bits are in user-MAT selection state when the
value other than H'AA is written and in user-boot-MAT selection state when H'AA is written.
The MAT is switched by writing the value in FMATS.
When the MAT is switched, follow section 17.27, Switching between User MAT and User Boot
MAT. (The user boot MAT cannot be programmed in user programming mode if user boot MAT
is selected by FMATS. The user boot MAT must be programmed in boot mode or in PROM
mode.)
