About This Manual
This manual describes the components of the TMS370 family application
board and contains the following chapters:
Chapter 1 Installing the Application Board and Invoking the Command Monitor.
Provides an overview and description of the functional blocks that compose
the TMS370 application board; tells you how to install the board and invoke
the command monitor.
Chapter 2 Master Operation. Discusses the functions of the master processor.
Chapter 3 Interfacing Between the Slave and the TMS370 Application Board.
Describes how the slave devices interface with the application board.
Chapter 4 Commands and Functions of the Command Monitor. Describes the
commands that you can use with the command monitor in TTY mode.
Appendix A Jumper and Switch Settings. Describes the location and function of each of
the jumpers and switches on the TMS370 application board.
Appendix B Using the TMS370 Assembly Language Tools With the Application
Board. Describes how the TMS370 assembler and code converter work with
the application board.
Appendix C Alphabetical Summary of Command-Monitor Messages. Describes
progress and error messages that the command monitor may display.
Appendix D Schematics. Contains schematics for the TMS370 family application board,
its spare gates, its power source, the master controller, the master/slave
buffer, the ’370Cx1x and ’370Cx5x slaves, the recreation ports, the protoarea
connections, and the PAL descriptions of the master and slave signals.
Appendix E Glossary. Defines acronyms and key terms used in this book.

Style and Symbol Conventions
iv
Style and Symbol Conventions
This document uses the following conventions.
- Program listings, program examples, interactive displays, filenames, and
symbol names are shown in a special typeface similar to a typewriter’s.
Examples use a bold version of the special typeface for emphasis;
interactive displays use a bold version of the special typeface to
distinguish commands that you enter from items that the system displays
(such as prompts, command output, error messages, etc.).
Here is a sample program listing:
.SECT ”TIUSE”,7FDEh ;specify a new memory section
.WORD 7FE0h ;Trap 0 vector
PUSH ST ;save status register
DINT ;stop all interrupts
BR 2000h ;goto master control interface
JMP $ ;used before WR and RR commands
RTI ;used before SS and RU commands
Here is an example of a system prompt and a command that you might
enter:
>LM 7000 700D 1 2 3 4
- In syntax descriptions, the instruction or command is in a bold face font,
and parameters are in
italics . Portions of a syntax that are in bold face
should be entered as shown; portions of a syntax that are in
italics
describe the kind of information that should be entered. Here is an
example of a command syntax:
DM
start [ stop ]
DM is the command. This command has two parameters, indicated by
start and stop .
- Square brackets ( [and ]) identify an optional parameter. If you use an
optional parameter, you specify the information within the brackets; you
don’t enter the brackets themselves. In the command syntax above,
stop
in an optional parameter.
- Braces( {and} )indicatealist.Thesymbol|(readas
or )separatesitems
within the list. Here’s an example of a list:
BL D {1|0}
Theregion andfill valueparametersfor theBL commandarenotoptional,
but you need to make a choice between 1 and 0.
