Microcontroller Programmer Overview and Description
1.1 Microcontroller Programmer Overview and Description
The TMS370 Microcontroller Programmer is an interactive, menu-driven system 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. T o 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
T o 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
in the device.
User-defined device types that allow new family members.
Ability to save or load the programmer configuration to or from a
configuration/batch file
In addition to these features, a limited batch mode is also supported.

Introduction and Installation
Microcontroller Programmer Overview and Description
The base unit of the programmer contains two LEDs. The red LED is marked
program
sockets. The green LED is marked
or
device power
and is lit whenever power is applied to device
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.

The gang programmer consists of the standard programmer base, a gang programmer 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 package of TMS370 microcontrollers.)

The main body of the gang programmer consists of 16 sockets whose type and
arrangement are dependent on the type of gang programmer top you have.
Below each socket is a red LED, which is used to indicate a failure of the device
in the socket immediately above the LED. These sockets are mounted on base
sockets to allow easy replacement if a socket is damaged.
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 program position.
There are two green LEDs on the left top of the gang programmer. The top LED

Typically , this programmer is used in PC mode to program initial units. However, 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 programmed, a checksum is calculated and added to the configuration information 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 additional 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 environment where you can easily program parts without the use of a personal computer; this is called standalone mode.

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 commands 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) 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.

1.3 Properly Installing the Programmer Hardware
Correctly installing the programmer hardware is essential to the proper operation of programmer system. The following subsections explain how to connect
the programming board to the PDS base unit and the required power connections for connecting your programmer to a PC or TMS370 XDS. Also included
in these subsections is a description of how to properly insert DIPs and PLCCs.
1.3.1 Connecting a Programmer to the PDS Base Unit
Connecting the programmer to the PDS is essentially the same for all programmers. The illustrations below show this process for the microcontroller programmer.
1) Line up the plastic tabs on the bottom of the programmer board with the
insertion hole in the top of the PDS base unit.
2) Press firmly until tabs are set.
3) Connect the ribbon cable from the PDS base unit to the connection on the
back of the programmer.

Introduction and Installation
1.3.2 Power Connection
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.
Properly Installing the Programmer Hardware
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 connector for your power receptacle. The wires are color coded as follows:
Green and Yellow = Earth
Blue = Neutral
Brown = Live
1.3.3 Connection to a PC
1) Connect the end of the RS-232C cable consisting of a single 25-pin connector 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/A T
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.

2) Connect port A of the XDS to the PC by using the cable supplied with the
XDS.
3) Ensure that the switches on the XDS Communications board are set as
in Table 1–1.

Introduction and Installation
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.

Note:
If you install a 2732 device in U2, be sure to use the bottom socket holes,
leaving the top four socket holes unused. The correct position for a 2732
is indicated by a bracket on the printed circuit board to the left of the socket.
Introduction and Installation
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.
T o 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 Microcontroller 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
This method is simple and suitable for a single user with only a few source files.
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 software.
1.4.2 Installing the Software in Multiple Directories
This method is useful if there are several different users or if one user is working 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 AUTOEXEC.BAT file.
PATH C:\DOS;C:\PROG;C:\REP;C:\370
where C:\370 is the added path to the programmer directory.

table. The order in which the programmer looks for the device table is outlined below.
a) First, it looks for a device table file specified in the configuration/batch
file if the configuration/batch file was included in the command line to
invoke the programmer software.
PRGRM370 @PROJ1.CFG
where PROJ1.CFG is the configuration/batch file.
b) Next, it looks in the current directory for the default DEVICE.TBL.
c) Then, it looks in the directory specified by the ”SET IPCDIR” command
for the file DEVICE.TBL.
6) See Section 1.5 for a description of how to invoke the programmer software.
1-15
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 programmer 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 programmed 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 parameters 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. Default 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,
the configuration specified in the file is loaded as the current configuration. Any
other batch commands that would control the flow of the programming process
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.
1-16
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. T o 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.
