Signal/Connection Descriptions
The MSC8101 external signals are organized into functional groups, as shown in Table 1-1, Figure 1-1, and
Figure 1-2. Table 1-1 lists the functional groups, the number of signal connections in each group, and
references the table that gives a detailed listing of multiplexed signals within each group. Figure 1-1 shows
MSC8101 external signals organized by function. Figure 1-2 indicates how the parallel input/output (I/O)
ports signals are multiplexed. Because the parallel I/O design supported by the MSC8101 Communications
Processor Module (CPM) is a subset of the parallel I/O signals supported by the MPC8260 device, port pins
are not numbered sequentially.
