Ethernet Interface

The DK2000 development platform includes a fast Ethernet port. The Ethernet port consists of a Level One

LXT970 Ethernet PHY connected to FCC3 of the MPC8260. The configuration of the Ethernet port is accomplished

using the general-purpose I/O pins of the MPC8260, making the DK2000 adaptable to the network environment.

Table 14 shows the I/O pins and their functions with the LXT970.
