3. Remove any rubber feet that may be attached to the EZ-KIT Lite.
In place of these rubber feet, install the 4 nylon feet and screws
provided with the USB-LAN EZ-Extender. Install the nylon feet in
the mounting holes of the EZ-KIT Lite’s PCB. Flip the EZ-KIT
Lite upside down so that the three expansion headers (J1–3) are
facing up.
4. Set the switches and jumpers on USB-LAN EZ-Extender board.
Use the block diagram in Figure 2-1 on page 2-2 in conjunction
with “Jumper Setting” on page 2-3 and “Switch Settings” on
page 2-6.
5. Set the switches and jumpers on EZ-KIT Lite board. If not already,
familiarize yourself with the documentation and schematics of the
EZ-KIT Lite (see “Related Documents”). Compare the expansion
interface signals of the USB-LAN EZ-Extender board with the signals of the EZ-KIT Lite board to ensure there is no contention. For
example, it may be necessary to disable other devices connected to
the expansion interface of the processor and disable the push buttons on the EZ-KIT Lite.
6. Install the USB-LAN EZ-Extender on the EZ-KIT Lite via the
three-connector expansion interface.
7. Configure any other interfacing boards, for example, another
EZ-Extender board.

USB 2.0 Interface
The USB-LAN EZ-Extender allows you to connect a USB 2.0 chip to a
Blackfin processor without any other programmable logic required. PLX’s
(formerly Netchip) Net2272 device ties directly to the Asynchronous
Memory Bank 3 of the Blackfin processor. You can read from and write to
the USB 2.0 controller by directly addressing the named memory bank.
You can reset the Net2272 processor by asserting LOW these flag pins: PF11
on the ADSP-BF533 processor, PF6 on the ADSP-BF537 processor, and
PF11 on the ADSP-BF561 processor.
The flag pins can be used for push buttons or LEDs on the respective
EZ-KIT Lite; consequently, the user must make the proper changes to
that EZ-KIT Lite. The switch settings required for each of the respective
EZ-KIT Lites are described in the USB Software Readme.txt file in the
...\Blackfin\EZ-KITs\USB-LAN EZ-EXTENDER\usb subdirectory of the VisualDSP++ installation directory. The readme file describes the USB
software, source code, drivers, and explains how to run a USB-based
application.

Optional ADSP-BF537 EZ-KIT Lite interfaces are:
• “Power-Over-Ethernet”
• “MII Interface”
Power-Over-Ethernet
The Blackfin USB-LAN EZ-Extender, when used in conjunction with the
ADSP-BF537 EZ-KIT Lite, allows a user to power both the EZ-KIT Lite
and the extender via a 10/100 Mbps switch or a Midspan device that supports IEEE802.3.AF.
Blackfin USB-LAN EZ-Extender
1-5
Optional ADSP-BF537 EZ-KIT Lite Interfaces
The EZ-KIT Lite and extender must not be powered via the 7.5V supply
when in Power-over-Ethernet mode. A user can make the appropriate
jumper changes to the EZ-KIT Lite and extender and then connect the kit
to the extender to power both boards via the switch or Midspan device.
The user must use a switch or Midspan device that supports power via the
data pairs. If a user uses a Midspan device that powers only over the spare
pins, then the PoE circuitry will not work.
Table 1-3 shows a recommended Midspan device that supports both
power over the spare pins and power over the data pairs.
Table 1-3. Midspan Device
Power Sourcing Equipment

Midspan Device
PowerDsine 6
PD-8006/AC
Use the Ethernet connector on the EZ-KIT Lite for the PoE application.
Power-over-Ethernet will not work properly if the Ethernet connector is
used on the extender board. When in PoE mode, the blinking LEDs
(LED[1:6]) confirm successful power-up. Since PoE is intended as a simple
demonstration of the power circuitry, you are not able to bring up a VisualDSP ++ session while in the Power-over-Ethernet mode.
Refer to “Power Select Jumper (JP1)” on page 2-3 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 also need to purchase the J2 connector and solder it to be able to connect the two boards together. The part numbers of the SMSC’s evaluation
boards and J2 connector are shown in Table 1-4.

FLAGS Enable Switch (SW1.2)
The Flags enable switch, SW2.2, is used to control the output of the Blackfin Flags multiplexer. By default, the SW1.2 switch is set to the ON position.
If is in the OFF position, the user cannot communicate to the USB or
Ethernet processor. The Flag enable switch adds flexibility to the
extender—when the switch is OFF, the Flags can be used for other peripherals of the EZ-KIT Lite.

USB IRQ Enable Switch (SW1.3)
The USB IRQ enable switch, SW1.3, is used to control the connection
between the Netchip 2272 IRQ line with the respective Flag pin on the
Blackfin processor. The switch connects the USB_IRQ line with PF10 on
the ADSP-BF533 and ADSP-BF561 processors, and PF7 on the
ADSP-BF537 processor. By default, the USB IRQ enable switch is in the
ON position. When in the OFF position, communication with the USB pro-

Serial ROM Enable Switch (SW2.1)
The Serial ROM enable switch, SW2.1, is used to control the connection
between the LAN91C111 Ethernet processor with its serial ROM (U3).
When the switch is disabled, the Ethernet processor loads its MAC address
from the serial ROM. The SW2.1 switch, by default, is set to the OFF position. If the switch is in the ON position, you are not able to communicate
with the Ethernet application code provided. The switch adds flexibility
to the extender—you can modify the application code and generate
another MAC address when the switch is ON.

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