Because of obvious differences between the microcontroller programmer and

the gang programmer, icons are used to distinguish descriptions and informa-

tionspecifictoeachtypeofprogrammer. Whentherearenoiconspresent, you

should assume the information is common to all programmers.

This icon is used to distinguish descriptions and information

specific to the microcontroller programmer.

This icon is used to distinguish descriptions and informa-

tion specific to the gang programmer.

When an icon is present, the information from the icon to the next icon, or to

Microcontroller Programmer Overview and Description

1.1 Microcontroller Programmer Overview and Description

The TMS370 Microcontroller Programmer is an interactive, menu-driven sys-

tem that facilitates programming TMS370 family devices and EPROMs either

directly or through an XDS. The microcontroller programmer is currently

capable of programming the TMS370, TMS7742, TMS77C82, 2732, 2764,

27128, and 27256 device families. To program the TMS7742 and TMS77C82

devices, you will need a 40-pin to 28-pin converter, which is sold separately.

Figure 1–1. Microcontroller Programmer Personality Module

To operate the programmer, create a COFF file using the TMS370 Assembler

and Linker on a PC. The programmer loads the object code from the COFF

file into PC memory and programs a device from the data in PC memory. The

device is programmed and verified in units (packets) of 180 bytes at a time.

The programmer software has the following features:

Window-oriented screens with a menu-driven command structure.

Intermediate PC memory, which provides a storage area for downloading

a COFF file or uploading from the device. This allows you to inspect and

patch the loaded data.

Reversed assembly code display.

Ability to generate a COFF file from PC memory content.

Relocatable programming capability, which allows source data bytes

within a certain address range to be programmed at a specified location

Microcontroller Programmer Overview and Description

The base unit of the programmer contains two LEDs. The red LED is marked

program or device power and is lit whenever power is applied to device

sockets. The green LED is marked power and indicates that the base is turned

on. This LED should turn on approximately three seconds after power is

supplied to the programmer.

Do not insert or remove devices from the programmer while the red

program (device power) LED is lit!

On the front edge of the programmer base is a black banana plug receptacle.

This is attached to the safety ground of the power cord in order to assist you

in connecting to electrostatic protection equipment.

Gang Programmer Overview and Description

1.2 Gang Programmer Overview and Description

The TMS370 Gang Programmer is an interactive, menu-driven system that

provides programming support for on-chip EEPROM or EPROM of TMS370

microcontrollers in production environments.

The gang programmer has the following features:

Two modes of operation—PC mode and standalone mode.

Ability to program up to 16 devices.

LEDs that indicate programming or verification failure.

A buzzer that indicates programming completion.

The gang programmer consists of the standard programmer base, a gang pro-

grammer top, and the standard programmer software. If you already have a

standard TMS370 Microcontroller programmer, the gang programmer top can

be purchased separately. (There is a different programmer top for each pack-

age of TMS370 microcontrollers.)

The rocker switch on the top center of the gang programmer board is used to

select program or verify when used in standalone mode; it is ignored in PC

mode. The red LED just above this switch is lit when the switch is in the pro-

gram position.

is marked PDS power on and indicates that the base unit is turned on. The low-

er LED is marked external power on and is used to indicate that the external

+15V is properly connected to the programmer top. The external power jack

is located on the upper left side of the programmer top.

Typically, this programmer is used in PC mode to program initial units. Howev-

er, you can use the 28-pin DIP socket at the top center of the programmer to

program a 27C512 EPROM as a master device. As the master device is pro-

grammed, a checksum is calculated and added to the configuration informa-

tion stored in the master device. This allows the programmer to verify that the

master device has not become corrupted before it is used to program addition-

al units. Once programmed, this master contains all of the configuration data

as well as the code to be programmed into the mocrcontrollers. Now, the gang

programmer with the master device can be moved to a production environ-

ment where you can easily program parts without the use of a personal com-

puter; this is called standalone mode.

Gang Programmer Overview and Description

1.2.1 Operating the Gang Programmer in PC Mode

In PC mode, the gang programmer is an interactive, menu-driven system that

facilitatesprogramming TMS370 family devices and EPROMs. The system al-

lows you to perform any or all of the operations listed below.

Program any or all of the 16 devices from PC memory

Modify or add a new device to the device table

Verify any or all devices against either PC memory or the master device.

Upload any of the 16 devices.

Program the 512K master device.

Upload the master device with or without configuration data.

Enter standalone mode.

When you program in PC mode, all LEDs are turned on for a predetermined

time as part of an LED test. Then, the software checks whether a device exists

in each socket and whether it is properly installed by running a small read-write

test. If any device fails, the LED for that device blinks for a few seconds, there

are two short audible beeps, and the following error message is displayed:

Device test failed, continue? (y/n)

If you have incorrectly inserted any device(s), you can fix them at this time. If

only empty sockets failed, you can continue the programming by pressing

The LED of the failed device(s) remains on during programming. At the end

of programming if there is a verification error on any other device, its LED turns

on also.

In the PC mode, the push button on the gang programmer is deactivated. The

interactive commands for this mode are discussed in Chapter 2 and 3.

The gang programmer’s ability to execute any or all of the programmer com-

mands on a master device allows you to program a master device for use in

standalone mode or to verify programmed devices against the master device

or PC memory while in PC mode.

1.2.2 Operating the Gang Programmer in Standalone Mode

In standalone mode, the programmer works without the PC interface. You can

access the stanalone mode from the PC mode by selecting the standalone

command; when the PC is not connected to the Gang Programmer during

power-up, standalone mode is automatically selected.

Standalone mode allows you to program and/or verify devices in a production-

type mode.

After you install the master 512K EPROM device and any devices you wish to

program or verify, the procedure for starting the programmer is quite simple.

Gang Programmer Overview and Description

1) Position the toggle switch to either the program position or the verification

position.

2) Press the push button on the programmer.

While you press the push button, all 16 LEDs turn on, and remain on to

verify LED operation, until you release the push button.

3) Release the push button to begin the programming or verification.

If any of the devices are bad or incorrectly inserted into a socket or if the

socket is empty, the programmer beeps twice, and the LED below the

socket begins blinking.

4) To resume programming/verification, press the push button (within a

2-second period).

5) If you want to correct the error, wait until the blinking LEDs stop blinking

but remain on. At this time, insert a new device (or reinsert the old device)

and try the programming/verification procedures again.

6) Once programming has begun, you can abort at any time by pressing the

push button.

If you try to program without a master or with an invalid master device, all 16

LEDs blink until you acknowledge the error by pressing the push button.

Properly Installing the Programmer Hardware

1.3 Properly Installing the Programmer Hardware

Correctly installing the programmer hardware is essential to the proper opera-

tion of programmer system. The following subsections explain how to connect

the programming board to the PDS base unit and the required power connec-

tions for connecting your programmer to a PC or TMS370 XDS. Also included

inthesesubsectionsisadescriptionofhowtoproperlyinsertDIPsandPLCCs.

1.3.1 Connecting a Programmer to the PDS Base Unit

ConnectingtheprogrammertothePDSisessentiallythesameforallprogram-

mers. The illustrations below show this process for the microcontroller pro-

grammer.

1) Line up the plastic tabs on the bottom of the programmer board with the

Properly Installing the Programmer Hardware

1.3.2 Power Connection

Connect the female end of the power cord to the PDS base unit.

The programmer can handle a power range of 105 to 265 volts AC at 47

to 440 hertz. All units are equipped with two power cords. If you are in the

U.S.A., use the power cord with a male connector that can be plugged

directly into a 120-V, 60-Hz power socket.

Outside the U.S.A., use the power cord with no male connector because

the type of receptacle to be used is unknown. Attach the appropriate con-

nector for your power receptacle. The wires are color coded as follows:

Green and Yellow = Earth

Blue = Neutral

Brown = Live

The gang programmer also requires an external power supply of 15 volts/2

amps. The connection for this external power is marked EXTERNAL POWER

and is positioned near the top left corner of the programmer’s socket board.

Plug the the jack of the +15-volt wire into the external power socket. Connect

the white-striped wire to the +15-volt terminal of the power supply and the solid

black wire to the ground terminal of the power supply.

1.3.3 Connection to a PC

1) Connect the end of the RS-232C cable consisting of a single 25-pin con-

nector to the programmer.

2) Connect the end of the RS-232C cable consisting of two 25-pin

connectors to the serial communication port of the PC. (If an IBM PC/AT

is used, the 9-pin-to-25-pin converter cable provided must be used.)

1.3.4 Connection to an XDS

Connect the programmer through an XDS if you want to use both the XDS

Debugger and the microcontroller programmer, and if the PC has only one

communication port. Or, even if you have enough communication ports but do

not want to change the port number when you switch from one tool to the other,

you can use this method. The programmer works as if it is connected directly

to the PC.

Complete the following steps to connect the programmer through an XDS.

1) Connect port D of an XDS to the programmer by using the RS-232C cable

supplied with the programmer. The male connector on the double-headed

end of the cable connects to the XDS; the single-headed end connects to

the programmer.

Properly Installing the Programmer Hardware

1.3.5 Integrated Circuit (IC) Insertion

ICs may be inserted or removed while power is applied to the programmer;

however:

1) When using the microcontroller programmer, never use

more than one IC socket at a time. Damage to the IC or the

programmer could result.

2) Never insert or remove the IC while the red LED is on. Dam-

age to the IC or the programmer could result.

3) TMS devices contain circuits to protect their inputs and out-

puts against damage due to electrostatic discharges of up to

2 kV. However, you should employ the usual precautions

when handling MOS devices, such as storing the device in

conductive foam and grounding yourself when handling

them.

For the microcontroller programmer, decide which of the sockets (U1, U2, U3,

U4, or U5) to use for your device. Figure 1–3, shows the circuit board and IC

sockets.

Properly Installing the Programmer Hardware

To install a PLCC device:

With this release of the programmers, the PLCC sockets do not have a lid;

therefore, they are not sensitive to the device package height. These new

sockets also have the pin 1 orientation at the top of each socket, making it less

likely for you to insert a device backwards.

1) Place the PLCC in the empty socket.

2) Press firmly until it is properly seated.

The programmer hardware is now ready to use.

To remove the device, press down firmly on the black plastic socket edges until

the device is pushed upward and released.

Properly Installing the Programmer Software

1.4 Properly Installing the Programmer Software

Installing software is exactly the same whether you are using the Microcontrol-

ler Programmer or the Gang Programmer. Insert the diskette supplied with the

programmer into the PC disk drive and use one of the following methods to

copy the contents of the diskette to a directory in your hard disk.

1.4.1 Installing the Software in a Single Directory

Thismethodissimpleandsuitableforasingleuserwithonlyafewsourcefiles.

1) Make a directory to contain your programmer files.

MKDIR \370

2) Change your working directory to the directory you just created.

CD \370

3) Copy the files from the diskette.

COPY A:*.*

4) See Section1.5 for a description of how to invoke the programmer soft-

ware.

1.4.2 Installing the Software in Multiple Directories

This method is useful if there are several different users or if one user is work-

ing on several different projects.

1) Create a directory for your programmer files.

MKDIR \370

2) Copy the programmer files into your programmer directory:

COPY A:*.* \370\*.*

3) Create project directories.

MKDIR \PROJ1

MKDIR \PROJ2

4) Add the programmer directory to the path command in the AUTOEX-

EC.BAT file.

PATH C:\DOS;C:\PROG;C:\REP;C:\370

where C:\370 is the added path to the programmer directory.

5) Include a set command in the AUTOEXEC.BAT file as follows:

SET IPCDIR=C:\370

If the device table cannot be found elsewhere, the set command causes

the programmer to search the programmer directory for the default device

Invoking the Programmer Software

1.5 Invoking the Programmer Software

Before activating the programmer, be sure that it is plugged in and correctly

connected as described in Section 1.3. Turn on the programmer’s power

switch (and the gang programmer’s external power) before invoking the pro-

grammer software.

The command to run the programmer software from the DOS prompt is:

prgrm370 [COFF file] [@Config./Batchfile] [–b] [–p=port #]

where

COFF file

Optional argument that specifies a file to be pro-

grammed or verified in the batch control mode or

loaded into PC memory in the interactive control

mode.

@Config./Batch file

Optional argument that specifies a configuration/

batch file that contains the configuration parame-

ters or the batch commands for the batch control

mode.

–b

Optional argument that turns on the batch mode if

specified.

–p = port #

The communication port number to be used. De-

fault is 1.

After you invoke the programmer software, the PC screen briefly displays a

version number and copyright message.

If you specified a configuration/batch file but did not turn on the batch mode,

theconfigurationspecifiedinthefileisloadedasthecurrentconfiguration. Any

otherbatchcommandsthatwouldcontroltheflowoftheprogrammingprocess

are ignored.

If you specified a configuration/batch file and turned on the batch mode with

the –b argument, the programmer software operates as directed by the batch

file.

If you specified a port number and the programmer is not physically connected

to that port, then the following error message is displayed.

Programmer not properly connected: Abort, Retry?

Aborting the invocation returns you to the DOS prompt. To retry the invocation,

make sure the programmer is turned on and properly connected to the port

specified in the command. Then, press

followed by

to restart the

programmer software.

Interactive mode commands are described in detail in Sections 2 and 3. Batch

commands are covered in Appendix 1.

1.6 Getting Started—Example Sessions

This section will help you get a quick start using your programmer. Once you

get started, the menu structure and prompts make the programmer easy to

learn and to use. The remainder of this manual provides a detailed reference

if you need further information on any of the commands, prompts, or error

messages. Use the Table of Contents at the front of the manual and the Index

at the end of the manual to direct you to the specific topic you need.

We assume that you are familiar with the TMS370 Assembler and Linker soft-

ware and that a COFF file has been created that contains object code with

which a device can be programmed. These are prerequisites to using the

programmers and is beyond the scope of this manual.

1.6.1 Interactive Programming Example 1

This example assumes that the programmer software has been loaded onto

your PC, and that the DOS prompt is C:>.

In this example you will invoke the programmer, choose a device to program,

and use the load command to give the programmer the name of the object file

and portion of the object code to be programmed onto the device.

1) From the DOS prompt, invoke the programmer to bring up the interactive

display in the configuration window.

1.6.2 Interactive Programming Example 2

This sample session illustrates entering the interactive mode with the COFF

fileautomaticallyloadedintoPCmemory. Iftheprogrammersoftwareisactive,

that is, in the display or configuration windows, press

to quit the program-

mer and verify your choice. This returns the DOS environment.

1) At the DOS prompt, type the following command:

C:\>prgrm370 xyz.out

where xyz.out is the name of the COFF file containing the object code with

which the device is to be programmed.

2) Press

. The programmer software will start and automatically load the

code in the xyz.out file into PC memory.

You can now operate the programmer in the interactive mode as usual.

This method saves a few steps in loading the COFF file if the default load

addresses are acceptable.

1.6.3 Batch Programming Example

This sample session illustrates batch mode programming. A configuration/

batch file (not to be confused with a DOS batch file) must exist in order to use

this method. If one does not, examine the detailed description in Appendix 1.

For this example, assume that your configuration/batch file is named abc.cfg.

If the programmer software is active, that is, in the display or configuration

windows, press

to quit the programmer and verify your choice. This returns

you to the DOS environment.

At the DOS prompt, type the following:

C:\>prgrm370 xyz.out @abc.cfg –b

where xyz.out is the COFF file and abc.cfg is the configuration/batch file. The

@ symbol is a delimiter identifying abc.cfg as a configuration/batch file, and

the –b symbol turns on the batch mode. If the –b had been left off, the interac-

tive mode would have been entered, and the configuration specified in the

abc.cfg file would be used.

For more information on the batch mode, see Appendix 1.

How Command Menus Work

2.1 How Command Menus Work

The interactive mode of the programmer is driven by commandmenus that are

displayed on the top line of the screen. A command menu is a list of command

names, each of which is displayed with one highlighted letter, usually the first

character in the name. The highlighted letter is the key you use to invoke the

command. You may type command letters in upper or lower case.

When you type a valid command letter, the programmer software clears the

command line, displays the name of the selected command, and executes the

command. Most commands require additional information, in which case the

programmer either prompts for parameters or displays a submenu of com-

mands.

Figure 2–1 shows the command menu structure. This figure is provided as a

road map to the desired command(s).

2.3 What Happens If I Make an Error?

If an error occurs, the programmer software displays an error message on the

bottom line of the screen and prompts you to hit any key to escape from the

error state. You can type any key, including

, on the keyboard. The mes-

sage is then cleared, and the function key line is redisplayed.

If the error was caused by an input to a prompt, the programmer software re-

turns to the prompt to let you re-enter a value. Otherwise, the software returns

to the next higher command menu.

Understanding Your Input at the Cursor Prompt

2.4 Understanding Your Input at the Cursor Prompt

The programmer software often requires you to enter a response to a prompt

or to move the cursor to a value on the screen and modify it.

The previous or default value for the prompted parameter value is always dis-

played. You can accept the displayed default or former value by pressing only

in response to the prompt.

If you type a new value, the characters are highlighted, and the cursor ad-

vances to the next field position. Only the highlighted characters are accepted

by the programmer. For example, assume that the displayed default value is

Configuration Window Overview and Description

The device table lists devices that can be programmed through the program-

mer. The device table displays 12 device types at a time and is sorted first by

the device family names and then by the device first names. If there is more

than one device type under one device family, the family name is displayed

only once, on the first line of the device family. When a new device is specified

or a device table is loaded from an outside file, the device table is automatically

updated. Iftheactualdevicetablecontainsmorethan12devicetypes, youcan

use the function keys to scroll through the table. When a current device is se-

lected, it is highlighted within the table.

The device table supplied with your programmer software includes all of the

TMS370 devices available at the time the programmer was produced. As new

configurations are made available, TI updates the DEVICE.TBL file and

makes it available through our microcontroller bulletin board system. For infor-

mation on how to use the bulletin board, contact the TMS370 hotline at the

number indicated on page 1-1.

2.6.1 Selecting the Proper Program Algorithm

For EEPROM memory in devices, there are three programming modes:

writing 0s only, all 1s in the data bytes are ignored.

writing 1s only, all 0s in the data bytes are ignored.

writing 0s and 1s.

For all other types of memory, writing 0s is the only programming mode.

The three modes provided for the TMS370 allow the selection of the most

efficient programming.

Whenthe1sand0smodeisused, theprogrammermakestwopassesthrough

the address range, programming the 1s in one pass and the 0s in the other

pass. Assume that the binary value 1010 1010 is to be programmed into a giv-

en address. First, the 1s are programmed, giving a value of 1x1x1x1x where

x is unknown (the previous contents of the location).

On the second pass, the 0s are programmed, resulting in x0x0 x0x0 where x

is a don’t care state (in this case 1s from the first pass) so that the resulting

value after both passes is 1010 1010, the desired value. This method is effec-

tive for modifying short segments of code.

If a large segment of code is to be modified, it will reduce programming time

by almost one half if you block erase to 1s and use the 0s-only mode.

When programming the EEPROM memory of TMS370 devices that also have

UV-erasable EPROMS, be sure to block erase the array before programming

the device. (Ultraviolet light causes the EEPROM bits to go to an intermediate

so that they must be block erased before programming.)

2.8 Defining and Adding a Device to the Device Table—the Add Device

Command

This command lets you define a new device type different from those in the

current device table, and then add it to the device table. When the add device

command is selected, the following programmer prompts appear.

Step 1: Identify the complete device name by answering the following two

prompts:

Device family name:

Device first name:

Legal device family names supported by the programmers are

TMS370, 2732, 2764, 27128, or 27256.

Device first names are names that distinguish different versions of

the same device family.

The programmer software checks the device table to make sure the

new device is not a duplication. If the new device is a duplicate, the

following error message is displayed.

duplicate device name (hit any key)

Press any key to erase the error message and return to the first

prompt to re-enter different device names.

Step 2: Identify the programming address range by answering the following

two prompts:

Device Program Ranges – Start Address: 0000h

Device Program Ranges – Size: 0000h

Enter numerical values within the range (0000h–FFFFh) to the ad-

dress prompts listed in Step 2.

Step 3: Identify the primary configuration parameters for the device by an-

swering the following four prompts:

Type of Memory:

Device VCC(in VDC – 0, 5 or 6) : 0

Device VPP (in VDC – 0, 5, 12, 12.5 or 21): 0

Program Algorithm:

If the family code is 10h (TMS370 EEPROM range), one of three pro-

gramming algorithms can be chosen—program 1s, program 0s, or

program 1s and 0s. Using this parameter along with the block erase

parameter, you can optimize for programming speed or can mini-

mize the number of write erase cycles. This parameter is ignored for

anyotherfamilycodeandshouldbesetto program 0s only forclarity.

After you have entered the program algorithm, the programmer repeats

the setup configuration starting at Step 2 to allow you to enter up to five

address blocks. Press
