Recommendable Memory Map
The recommendation logic address memory map at the time of varieties extension
memory correspondence is shown in Figure 3.8.1. And, a physical-address map is shown
in Figure 3.8.2.
However, when memory area is less than 16 Mbytes and is not expanded, please refer to
section of CS/WAIT controller. Setting of register in MMU is not necessary.
Since it is being fixed, the address of a local area cannot be changed.
