The linker depicts the memory of the ZNEO CPU using a hierarchical memory model con-
taining spaces and segments. Each memory region of the CPU is associated with a space.
Multiple segments can belong to a given space. Each space has a range associated with it
that identifies valid addresses for that space. The hierarchical memory model for the
ZNEO CPU is shown in Figure 128. Figure 129 depicts how the linker links and locates
segments in different object modules.
For a more detailed description of the linker and the various commands it supports, see the
Using the Linker/Locator chapter on page 259.
