Figure 23. Logical Address Mapping Examples
Logical to Physical Address Translation
Figure 24 illustrates an example in which the three logical address space
portions are mapped into a 1024KB physical address space. The
important points to note are that Common and Bank Areas can overlap
and that Common Area 1 and Bank Area can be freely relocated (on 4KB
physical address boundaries). Common Area 0 (if it exists) is always
based at physical address
00000H
