1.1 Signal Groupings
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.
