1.1Microcontroller 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.

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 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.
