Geographic Addressing
CompactPCI backplanes that support 64-bit connector pin assignments are required to provide a unique
differentiation based upon which physical slot the board has been inserted. The CPCI-824 makes this
definition available to the software. The definition for GA[4:0] is shown in Figure 2.3.
