The microcontroller programmer is currently capable of programming the TMS370, TMS7742, TMS77C82, 2732, 2764, 27128, and 27256 device families.
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.
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.
Gang Programmer Overview and Description alone mode; it is ignored in PC mode. The red LED built into this switch is marked TMS370 power on and indicates that power is being supplied to the sockets on the gang programmer. Do not insert or remove devices from the programmer while the red TMS370 power on LED is lit! 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.
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 facilitates programming TMS370 family devices and EPROMs. The system allows 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.
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.
Properly Installing the Programmer Hardware 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.
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.
Properly Installing the Programmer Hardware 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. Table 1–1. XDS Memory Expansion/Communications Board Switch Settings 1-10 Switch No.
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. Damage to the IC or the programmer could result.
Properly Installing the Programmer Hardware To install a DIP device: 1) Align the IC so that pin 1 is oriented in the upper-left corner, indicated on the printed circuit board by a circled number 1: 2) Raise the locking arm, pulling it toward you to the upright position. 3) Insert the IC. locking arm DIP 4) Lower the locking arm by pushing it away from you and down, as far as it will go.
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.
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.
Properly Installing the Programmer Software 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.
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.

Appendix A Operating the Programmer in Batch Mode In the batch control mode, the execution flow is defined in a configuration/ batch file, and all messages are displayed in line-oriented mode. The configuration/batch file consists of a set of commands that define the current configuration and give direction of execution. Section Page A.1 Understanding the Batch Mode File . . . . . . . . . . . . . . . . . . . . . . . . . A-2 A.2 Batch File Command Rules and Descriptions . . . . . . . . . . . . . . . . .
Understanding the Batch Mode File A.1 Understanding the Batch Mode File Batch mode allows you to program and/or verify devices repeatedly with a fixed configuration setup in the configuration/batch file. When you invoke the programmer in batch mode, all device parameters are specified by the device type called out in the configuration/batch file. The configuration/batch file is an ASCII file that calls out the device table and device type.
Batch File Command Rules and Descriptions A.2 Batch File Command Rules and Descriptions The batch commands can be classified as executable or nonexecutable. The executable commands invoke operations, whereas the nonexecutable commands define programming parameters and the device type. The batch commands must conform to the following basic syntax rules: 1) Lower case and upper case characters are not distinguished. 2) Only one command is allowed on each line.
Batch File Command Rules and Descriptions A.2.2 Nonexecutable Batch Commands Nonexecutable commands do not invoke any action. They set certain programming parameters and define the device type. These commands can be classified as defaultable or nondefaultable. Defaultable commands are not required in the configuration/batch file; the commands have their own default values if not specified. Nondefaultable commands must be specified in the configuration/batch file because no default is provided.
Batch Mode Status Messages A.3 Batch Mode Status Messages When programming begins, a status message informs you: Programming at device address where device address is the location on the device that is currently being programmed. This message is updated every time the programmer starts on the next packet of data. A similar message appears when verification begins: Reading at device address where device address is the location on the device that is currently being read and verified.

Appendix B Error Messages This appendix briefly describes the error messages associated with the programmers. It also gives reasons why the error occurred and suggestions on how to fix the error. The messages are arranged in alphabetic order.
Error Message Descriptions B.1 Error Message Descriptions The following messages are common to all programmers. Chip inserted incorrectly, or bad – Retry, Abort For the microcontroller programmer, this message refers to the 2732, 2764, 27128, and 27256 devices. For the gang programmer, this message refers to the master EPROM device. Re-insert the device or replace the device with a new one.
Error Message Descriptions invalid Vcc chosen – Retry, Abort The VCC value you have chosen for your device is invalid. Use a valid VCC value—0, 5, or 6 volts. invalid VPP chosen – Retry, Abort The VPP value you have chosen is invalid. Use a valid VPP value—0, 5, 12, 12.5, or 21 volts. unable to communicate with TMS370 device – Retry, Abort The programmer is unable to communicate with the TMS370 microcontroller. The microcontroller may have bent pins, may be inserted incorrectly, or may be inoperable.
Error Message Descriptions These error messages are specific to the gang programmers. checksum error in master device – Retry, Abort The data in the master device is corrupt. Replace the master EPROM. illegal memory type detected in master – Retry, Abort The master EPROM device has illegal configuration data. Replace the master EPROM. Invalid master configuration data The configurable data of the master device is corrupt, or else the master device is blank. Replace the master EPROM.
Appendix C Configuration Parameters Table C–1 describes the valid configuration parameters for the programmers discussed in this manual. Use of invalid parameters will result in programming errors.

Appendix D Using Keystroke Capture Files A keystroke capture file is a file in which the keystrokes you type are recorded to be replayed later. Keystroke capture files are useful in setting up the programmer to perform a commonly repeated program or to verify operation. Two command line switches allow the recording and replaying of keystroke files, and a control character allows you to turn off recording of a keystroke file. /Cfilename.ext records keystrokes into file fliename.ext /Kfilename.
