R/W 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.)
H'AA: The user boot MAT is selected (in user-MAT
selection state when the value of these bits are
other than H'AA)
Initial value when these bits are initiated in user
boot mode.
H'00: Initial value when these bits are initiated in a mode
except for user boot mode (in user-MAT selection
state)
[Programmable condition]
These bits are in the execution state in the on-chip RAM.
Note: * Set to 1 when in user boot mode, otherwise set to 0.
