3.8Debug Interface

3.8.1Console Serial Port

The platform has one serial port for debug purposes as described in Section 3.7, “Intel® IQ80219 Evaluation Platform Board Peripheral Bus” on page 38.

3.8.2Ethernet Port

The IQ80219 supports an Intel® 82544EI Gigabit Ethernet Controller on the secondary PCI-X bus.

3.8.2.1Intel® 82544EI Gigabit Ethernet Controller

The Intel® 82544EI Gigabit Ethernet Controller is an integrated third-generation Ethernet LAN component capable of providing 1000, 100, and 10 Mb/s data rates. It is a single-chip device, containing both the MAC and PHY layer functions, and optimized for LAN on Motherboard (LOM) designs, enterprise networking, and Internet appliances that use the Peripheral Component Interconnect (PCI) and PCI-X bus back-planes.

The 82544EI utilizes a 32/64-bit, 33/66 MHz direct-interface to the PCI bus, compliant with the PCI Local Bus Specification, Revision 2.2. It also supports the PCI-X Addendum to the PCI Local Bus Specification, Revision 1.0a. The controller interfaces with the 80219 through on-chip command/status registers and using a shared memory area.

The physical layer circuitry provides an IEEE 802.3 Ethernet interface for 1000BASE-T, 100BASE-TX and 10BASE-T applications.
