Figure 10-4 shows an example topology for a single BMC and a single NC package. In this example, the
NC package has two NC channels.
Figure 10-5 shows an example topology for a single BMC and two NC packages. In this example, one
NC package has two NC channels and the other has only one NC channel. Scenarios in which the NC-SI
lines are shared by multiple NCs (Figure 10-5) mandate an arbitration mechanism.
