11.4.1 Memory Address Map Select Register (MMSELR) MMSELR is a 32-bit register that selects memory address maps for areas 2 to 5. This register should be accessed at the address H'FC40 0020 in longword. To prevent incorrect writing, writing is accepted only when the upper 16-bit data is H'A5A5. The upper 29 bits are always read as 0. This register is initialized to H'0000 0000 by a power-on reset or a manual reset.
