6.4.4
The initial state of each area is basic bus interface, three-state access space. The initial bus width is
selected according to the operating mode.
Areas 0 to 6: In the H8/3008, the entire space of areas 0 to 6 is external space.
When area 0 to 6 external space is accessed, the CS
The size of areas 0 to 6 is 128 kbytes in modes 1 and 2, and 2 Mbytes in modes 3 and 4.
Area 7: Area 7 includes the on-chip RAM and internal I/O registers. In the H8/3008, the space
excluding the on-chip RAM and I/O registers is external space. The on-chip RAM is enabled when
the RAME bit in the system control register (SYSCR) is set to 1; when the RAME bit is cleared to
0, the on-chip RAM is disabled and the corresponding space becomes external space .
When area 7 external space is accessed, the CS
The size of area 7 is 128 kbytes in modes 1 and 2, and 2 Mbytes in modes 3 and 4.
