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.
