Processor Land Assignments

This section contains the land listings for the processor. The land-out footprint is shown

Figure 4-1

and

Figure 4-2

. These figures represent the land-out arranged by land

number and they show the physical location of each signal on the package land array

(top view).

Table 4-1

is a listing of all processor lands ordered alphabetically by land

(signal) name.

Table 4-2

is also a listing of all processor lands; the ordering is by land

number.
