3.1 Overview of Schematics
The board has been designed to allow an AMBA bus master (such as an ARM7TDMI test
chip) to be mounted on daughter board. The daughter board is an integral part of the ARM
Development Board, although the daughter board supplied could be replaced with another
AMBA master, such as an in-circuit emulator.

3.1.2 Configuring the board
The board is configurable through the use of links, jumpers and switches. Each of these is
described in detail in the following subsections. In addition, there is a summary of links and
switches in
Appendix D, Summary of Jumpers and Links
. Also, the
Target Development
System User Guide (ARM DUI 0061)
contains information on configuring the ARM
Development Board.
