Large block 7 to 0
0 Block LB7 to LB0 is not selected (Initial value)
1 _{Block LB7 to LB0 is selected}
Note: * The initial value is H'00 in modes 5, 6 and 7 (on-chip flash memory enabled). In modes
1, 2, 3, and 4 (on-chip flash memory disabled), this register cannot be modified and is always
read as H'FF.
