CHAPTER 2 CPU
2.2
Memory Space
An F
2
MC-16LX CPU has a 16-Mbyte memory space. All data program input and output
managed by the F
2
MC-16LX CPU are located in this 16-Mbyte memory space. The CPU
accesses the resources by indicating their addresses using a 24-bit address bus.
■
Outline of CPU Memory Space
All I/O, programs and data are located in the 16-megabyte memory space of the F
2
MC-16LX CPU. The
CPU is able to access each resource through an address indicated by the 24-bit address bus.
Figure 2.2-1 shows a sample relationship between the F
2
MC-16LX system and memory map.
