Regulatory Compliance
The ADSP-BF561 EZ-KIT Lite is designed to be used solely in a labora-
tory environment. The board is not intended for use as a consumer end
product or as a portion of a consumer end product. The board is an open
system design which does not include a shielded enclosure and therefore
may cause interference to other electrical devices in close proximity. This
board should not be used in or near any medical equipment or RF devices.
The ADSP-BF561 EZ-KIT Lite has been certified to comply with the
essential requirements of the European EMC directive 89/336/EEC
amended by 93/68/EEC and therefore carries the “CE” mark.
The ADSP-BF561 EZ-KIT Lite has been appended to Analog Devices,
Inc. Technical Construction File (TCF) referenced ‘DSPTOOLS1’ dated
December 21, 1997 and was awarded CE Certification by an appointed
European Competent Body as listed below.
Technical Certificate No: Z600ANA1.016
Issued by: Technology International (Europe) Limited
60 Shrivenham Hundred Business Park
Shrivenham, Swindon, SN6 8TY, UK
The EZ-KIT Lite evaluation system contains ESD (electrostatic discharge)
sensitive devices. Electrostatic charges readily accumulate on the human
body and equipment and can discharge without detection. Permanent
damage may occur on devices subjected to high-energy discharges. Proper
ESD precautions are recommended to avoid performance degradation or
loss of functionality. Store unused EZ-KIT Lite boards in the protective
shipping package.

ADSP-BF561 EZ-KIT Lite Evaluation System Manual ix
PREFACE
Thank you for purchasing the ADSP-BF561 EZ-KIT Lite®, Analog
Devices, Inc. evaluation system for Blackfin®processors.
Blackfin processors support a media instruction set computing (MISC)
architecture. This architecture is the natural merging of RISC, media
functions, and digital signal processing (DSP) characteristics. Blackfin
processors deliver signal-processing performance in a microprocessor-like
environment.
The evaluation board is designed to be used in conjunction with the Visu-
alDSP++®development environment to test the capabilities of the
ADSP-BF561 Blackfin processors. The VisualDSP++ development envi-
ronment gives you the ability to perform advanced application code
development and debug, such as:
• Create, compile, assemble, and link application programs written
in C++, C, and ADSP-BF561 assembly
• Load, run, step, halt, and set breakpoints in application programs
• Read and write data and program memory
• Read and write core and peripheral registers
• Plot memory
Access to the ADSP-BF561 processor from a personal computer (PC) is
achieved through a USB port or an optional JTAG emulator. The USB
interface gives unrestricted access to the ADSP-BF561 processor and the
evaluation board peripherals. Analog Devices JTAG emulators offer faster

communication between the host PC and target hardware. Analog Devices
carries a wide range of in-circuit emulation products. To learn more about
Analog Devices emulators and processor development tools, go to
http://www.analog.com/dsp/tools/.
The ADSP-BF561 EZ-KIT Lite provides example programs to demon-
strate the capabilities of the evaluation board.
LThe ADSP-BF561 EZ-KIT Lite installation is part of the Visu-
alDSP++ installation. The EZ-KIT Lite is a licensed product that
offers an unrestricted evaluation license for the first 90 days. For
details about evaluation license restrictions after the 90 days, refer
to “Evaluation License Restrictions” on page 1-7 and the Visu-
alDSP++ Installation Quick Reference Card.

• Analog Devices ADSP-BF561 Blackfin processor
D256-pin mini-BGA package
D30 MHz CLKIN oscillator
• Synchronous dynamic random access memory (SDRAM)

The EZ-KIT Lite board holds 8 MB of flash memory, which can be used
to store user-specific boot code, allowing the board to run as a stand-alone
unit. The board also holds 512-Mb SDRAM, which can be used at runt-
ime. For more information see “Memory Map” on page 1-7.
SPORT0 interfaces with the AD1836A audio codec, facilitating creation of
audio signal processing applications. SPORT0 also attaches to an off-board
connector to allow communication with other serial devices. For informa-
tion about SPORT0, see “SPORT Audio Interface” on page 2-3.

Purpose of This Manual
xii ADSP-BF561 EZ-KIT Lite Evaluation System Manual
The parallel peripheral interfaces (PPIs) of the processor connect to both a
video encoder and video decoder, facilitating creation of video signal pro-
cessing applications. For information on how the board utilizes the
processor’s PPIs, see “PPI Interfaces” on page 2-6.
The UART of the processor connects to an RS-232 line driver and a DB9
male connector, allowing you to interface with a PC or other serial device.
For information about the UART, see “UART Port” on page 2-8.
Additionally, the EZ-KIT Lite board provides access to most of the pro-
cessor’s peripheral ports. Access is provided in the form of a
three-connector expansion interface. For information about the expansion
interface, see “Expansion Interface” on page 2-8.
Purpose of This Manual
The ADSP-BF561 EZ-KIT Lite Evaluation System Manual provides
instructions for installing the product hardware (board). The text
describes operation and configuration of the board components and pro-
vides guidelines for running your own code on the ADSP-BF561 EZ-KIT
Lite. Finally, a schematic and a bill of materials are provided as a reference
for future designs.
The product software installation is detailed in the VisualDSP++ Installa-
tion Quick Reference Card.
Intended Audience
The primary audience for this manual is a programmer who is familiar
with Analog Devices processors. This manual assumes that the audience
has a working knowledge of the appropriate processor architecture and
instruction set. Programmers who are unfamiliar with Analog Devices
processors can use this manual but should supplement it with other texts
