CHAPTER 3 CPU
3.2
Memory Space
All I/O, programs and data are located in the 16-megabyte memory space of the F
2
MC-
16LX. A part of the memory space is used for special purposes, such as extended
intelligent I/O service (EI
2
OS) descriptors, general-purpose registers and vector tables.

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 3.2-1 shows a sample relationship between the F
2
MC-16LX system and the memory map.
