FR Family Memory Space

The FR family controls memory space in byte units, and provides linear designation of
32-bit spaces. Also, to enhance instruction efficiency, specific areas of memory are
allocated for use as direct address areas and vector table areas.

Figure 2.1-1 illustrates memory space in the FR family.
For a detailed description of the direct address area, see Section "2.1.1 Direct Address Area", and for the
vector table area, see Section "2.1.2 Vector Table Area".
