Enables or disables CPU access for flash memory
registers (FLMCR1, FLMCR2, EBR1, EBR2), control
registers in power-down state (SBYCR, LPWRCR,
MSTPCRH, MSTPCRL), and control registers of on-
chip peripheral modules (PCSR, SYSCR2).
0: Registers in power-down state and control
registers of on-chip peripheral modules are accessed
in an area from H'(FF)FF80 to H'(FF)FF87.
1: Control registers of flash memory are accessed in
an area from H'(FF)FF80 to H'(FF)FF87.
