Regulatory Compliance
The ADSP-BF537 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-BF537 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-BF537 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: Z600ANA1.021
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.

PREFACE
Thank you for purchasing the ADSP-BF537 EZ-KIT Lite®, Analog
Devices, Inc. evaluation system for Blackfin®processors.
Blackfin processors embody a type of embedded processor designed specif-
ically to meet the computational demands and power constraints of
today’s embedded audio, video, and communications applications. They
deliver breakthrough signal-processing performance and power efficiency
within a reduced instruction set computing (RISC) programming model.
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.
Based on the Micro Signal Architecture (MSA), Blackfin processors com-
bine a 32-bit RISC instruction set, dual 16-bit multiply accumulate
(MAC) DSP functionality, and 8-bit video processing performance that
had previously been the exclusive domain of very-long instruction word
(VLIW) media processors.

x ADSP-BF537 EZ-KIT Lite Evaluation System Manual
The evaluation board is designed to be used in conjunction with the
CrossCore®Embedded Studio (CCES) and VisualDSP++®development
environments to test the capabilities of the ADSP-BF537 Blackfin proces-
sors. The development environment 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-BF537 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-BF537 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-BF537 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-BF537 EZ-KIT Lite provides example programs to demon-
strate the capabilities of the evaluation board.
