The MSC8122 external signals are organized into functional groups, as shown in Table 1-1 and Figure 1-1.

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 MSC8122 external signals

organized by function.
