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.
