2.14 Memory Map
Figure 2-3 on page 2-35 and Figure2-2 on page 2-34 show the full processor memory map.
Any unused register space from 0x4000 0000 to 0x4BFF FFFF is reserved.
Note: Accessing reserved portio ns of the memory map gives unp redictable results.
The PCMCIA interface is divided into socket 0 and socket 1 space. These two partitions are each
subdivided into I/O, memory and attribute space. Each is allocated 128 MB of memory space.
