Notes: Do not access reserved space, as operation cannot be guaranteed in this case.
In single-chip mode, space other than on-chip ROM, on-chip RAM, and on-chip peripheral
module space cannot be used.
1. Selected by on-chip register settings.
2. Ordinary space: selected by on-chip register settings.
Multiplex I/O space: 8/16 bits selected by the A14 bit.
3. 8/16 bits selected by the mode pin.
4. In the 64-kbyte on-chip ROM version (SH7016), on-chip ROM addresses are
H'00000000 to H'0000FFFF, and addresses H'00010000 to H'0001FFFF are reserved
space.
5. SH7016/17 only.
6. In the 3-kbyte on-chip RAM versions (SH7014/16), on-chip RAM addresses are
H'FFFFF000 to H'FFFFFBFF, and addresses H'FFFFFC00 to H'FFFFFFFF are
reserved space.
