Use the Ethernet connector on the EZ-KIT Lite for PoE applications.
Power-over-Ethernet does not work properly if the Ethernet connector is
used on the extender board. When in PoE mode, the blinking LEDs
(LED1–6]) confirm successful power-up. Since PoE is intended as a simple
demonstration of the power circuitry, you are not able to start a VisualDSP ++ session while in PoE mode.
Refer to “Power Select Jumper (JP1)” on page 2-4 for the extender’s PoE
settings. Refer to the ADSP-BF537 EZ-KIT Lite Evaluation System Manual
for the EZ-KIT Lite’s PoE settings.
MII Interface
The Media Independent Interface (MII) allows you to evaluate different
PHY devices with the ADSP-BF537 EZ-KIT Lite. A separately purchased
PHY evaluation board connects directly to the USB-LAN EZ-Extender.
You need to purchase the J2 connector and solder it in order to connect
the two boards. The part numbers for the SMSC evaluation boards and J2
connector are shown in Table 1-4.

switch is OFF, the flags can be used for other peripherals on the EZ-KIT
Lite.

USB IRQ Enable Switch (SW1.3)
The USB IRQ enable switch, SW1.3, is used to control a connection
between the Netchip 2272 IRQ line and respective flag pin of the Blackfin
processor (see Table 2-6). The switch connects the USB_IRQ line with PF10
on the ADSP-BF533/ADSP-BF561 processor and PF7 on the
ADSP-BF537 processor. By default, the USB IRQ enable switch is ON.
When SW1.3 is OFF, communication with the USB device cannot be established. The SW1.3 adds flexibility to the extender—when the switch is OFF,
the flag can be used for other peripherals on the EZ-KIT Lite.

Serial ROM Enable Switch (SW2.1)
The serial ROM enable switch, SW2.1, is used to control a connection
between the LAN91C111 Ethernet chip and its serial ROM (U3) (see
Table 2-8). When the switch is disabled, the Ethernet chip loads its Media
Access Control (MAC) address from the serial ROM. By default SW2.1 is
OFF. When the switch is ON, you cannot communicate with the provided
Ethernet application code. The switch adds flexibility to the extender—
you can modify the application code and generate another MAC address
when SW2.1 is ON.

IOS[2:0] Switch (SW2.2, SW2.3, SW2.4)
The IOS[2:0] bits on the Blackfin USB-LAN EZ-Extender are connected
directly to the IOS[2:0] pins of the LAN91C111 Ethernet chip. By
default, the switches are OFF. The IOS[2:0] pins are used in conjunction
with the Serial ROM Enable Switch (SW2.1) to select between the predefined EEPROM configurations. For more information about the
switches, refer to the SMSC LAN91C111 data sheet.
