MOTOROLA DSP56824ADMUser’sManual 1-3
1.1 DSP56824ADM OVERVIEW
The DSP56824 Application Development Module (DSP56824ADM) was designed to
operate with the Motorola Application Development System (ADS). Use of the
DSP56824ADM with the Motorola ADS facilitates development, debug, and test of
complex software applications and hardware products designed for the DSP56824.
Detailed information about the Motorola ADS is provided in the Motorola ADS User’s
Manual (order # DSPADSUM/AD).
Subsection 1.2 of this document gives a summary description of the equipment required
to use the module with the Motorola ADS.
Subsection 1.3 describes installation instructions, including the following:
• Preparing the module for installation
• Installing the module
• Installing the software
• Testing the installation
Note: Detailed information about the design and operation of the DSP56824ADM is
provided in this manual in Section 2 and Appendices A and B.
1.2 REQUIRED USER-SUPPLIED EQUIPMENT
For use with the Motorola ADS (and the appropriate interface card), the user must
supply one of the following host computer systems:
• PC-compatible computer (486 class or higher) with the following:
– MS-DOS version 6.0 or later, Windows 3.1 or later, or Windows 95
– 8 Mbytes RAM
– One open 16-bit ISA expansion slot
– One bank of free I/O addresses in the range of $100–$102, $200–202, or

not supported), one open EISA expansion slot, CD-ROM drive, and a mouse
• Sun Microsystems Sun 4 Workstation running Sun Operating System Release
4.1.1 or later (or Solaris Release 2.5 or later), one open SBus expansion slot, a
CD-ROM drive, and a mouse
1.3 INSTALLATION PROCEDURE
Installation requires four basic steps:
1. Preparing the DSP56824ADM board
2. Installing the module
3. Installing the software
4. Testing the installation
1.3.1 Preparing the DSP56824ADM
Locate the jumper blocks JG1–JG17 on the DSP56824ADM board, as shown in Figure 1-1.
Table 1-1 describes the jumper group settings for use with the Motorola ADS. Read the
CAUTION
Because all electronic components are sensitive to the effects of
electrostatic discharge (ESD) damage, correct procedures should be
used when handling all components in this kit and inside the
supporting personal computer. Use the following procedures to
minimize the likelihood of damage due to ESD:
– Always handle all static-sensitive components only in a protected area,
preferably a lab with conductive (anti-static) flooring and bench surfaces.
– Always use grounded wrist straps when handling sensitive components.
– Never remove components from anti-static packaging until required for
installation.
– Always transport sensitive components in anti-static packaging.
