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.
