Note 1: Boot program (Internal MROM) is mapped only for BOOT mode. For other starting modes, its area (3FE000H to 3FFFFFH)
is mapped to external-memory.
Note 2: The Provisional emulator control area, mapped F00000H to F0FFFFH after reset, is for emulator use and so is not available.
When emulator WR signal and RD signal are asserted, this area is accessed. Ensure external memory is used.
Note 3: Do not use the last 16-byte area (FFFFF0H to FFFFFFH). This area is reserved for an emulator.
