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\Examples\USB-LAN EZ-EXTENDER\USB
subdirectory of the
Vi+ installation directory. The readme file describes the USB
software, source code, drivers, and explains how to run a USB-based
application.

For correct switch settings, refer to the schematics drawing of the
respective device.
