2 DSPAUDIOEVM Evaluation Board Users Manual MOTOROLA
This document contains information on a new product. Specifications and information herein are subject to change without notice.
The motherboard uses an included external universal power supply (100-220VAC, 50-60 Hz). The power
supply uses an IEC three pin power connector for the AC supply. The user must supply the AC cable
required to connect power to the region specific AC power connection.
1.3 Debugger Interfaces
1.3.1 Suite56 OnCE

Debugger
The motherboard also supports multiple debugger interfaces. The Motorola high speed parallel port OnCE
command converter tool is embedded in the EVM (no special cables are required). An IEEE 1284 Parallel
port cable is included in the EVM kit for convenience.
This OnCE interface can be used with the Motorola Suite56 tool set software and documentation available
at http://www.metroworks.com/MW/Develop/Embedded/suite56.htm
1.3.2 Symphony Debugger Interface
In addition to OnCE debugging, the motherboard includes a real time Symphony Debugger Interface (SDI).
This debugger uses either a RS-232 or USB interface and allows SPI or I
2
C communication to the DSP from
a PC for real time debugging and configuration of the DSP. The software and documentation to enable use
of the SDI debugger are available off the Web:
http://e-www.motorola.com/webapp/sps/site/prod_summary.jsp?code=DSPAUDIOEVM&nodeld=10279539058775#
or go to
http://www.motorola.com, search for DSPAUDIOEVM, and follow the links to the user’s manual.
Note: The SDI software is primarily designed for users of ROMed Software Architecture DSPs,
and it is not the best tool to use for generic DSPs.
1.4 Microcontrollers
There are two HC08 Motorola microcontrollers included in this EVM. They each have a dedicated function
and are re-flashable in the event a field upgrade is required to the EVM.
1.5 Config MPU
This is an HC908GP32 microcontroller and is pre-programmed with software to enable all of the on-board
AKM components and clocking mode changes. This microcontroller also controls the mute functionality of
the final audio outputs and the switching of the inputs sourced to the DSP daughterboard.
1.6 Debug MPU
This is an HC908JB16 and is pre-programmed with software to allow communication (from a host PC to
the DSP) via the serial RS232 and USB ports in conjunction with the supplied SDI debugger software.
1.7 Getting Started
The first step to using your EVM system is to insert the daughterboard into the motherboard. The connectors
are keyed to be inserted in only one direction, but for reference the Motorola white silkscreen should be
oriented identically on the motherboard and daughterboard.
Connecting the power supply is the next step and we recommend always using a grounded AC power cord
for both improved audio performance and safety. Connect the power supply to the AC power source first
and then to the EVM at the round J1 connector. When the connector is properly seated, all five of the power
LEDs located next to the J1 connector should be illuminated.
