Spaces other than on-chip ROM, on-chip RAM, and on-chip peripheral modules cannot be
used in single-chip mode.
1. Selected by setting the on-chip register.
2. Selected by the mode pin: 8 or 16 bits in SH7144 (112 pins)
16 or 32 bits in SH7145 (144 pins)
3. Spaces CS4 to CS7 are available only for the masked ROM version and ROMless
version. These spaces are reserved for the flash memory version and emulator.
