2.2.2 Memory-Map Table
The control and status registers for each module are mapped within the CPU’s 4GB memory space. Some
modules also have associated memories, which are also mapped within this space.
Table 2-2 shows the starting and ending addresses of each module’s register frame and any associated
memory. The table also shows the response generated by the module or the interconnect whenever an
access is made to an unimplemented location inside the register or memory frame.
