1. INTRODUCTION<br />
This manual will guide you through the installation and operation of the<br />
XPROG-m with <strong>TMS374</strong> in-circuit programming (ICP) adapter. The<br />
<strong>TMS374</strong> ICP adapter has been designed for Reading, Programming of<br />
<strong>TMS374</strong> internal EEPROM contents.<br />
2. REQUIREMENTS<br />
The following describes what items are required for <strong>TMS374</strong> in-circuit<br />
programming.<br />
• XPROG-m programmer board (P/C: 1-001-0002)<br />
• <strong>TMS374</strong> family in-circuit programming adapter (P/C: 1-002-0008)<br />
• Power supply 15Vdc/300mA<br />
• Device Programmer Desktop V4.2 or higher (P/C: 2-001-0001)<br />
• TMS370/<strong>TMS374</strong> family authorization (P/C: 2-002-0005)<br />

3. TARGET CONNECTION<br />
This section contains overall information about ICP interface and description<br />
how to connect <strong>TMS374</strong> MCU family.<br />
3.1. ICP interface<br />
In-Circuit Programming interface is basic for <strong>TMS374</strong> ICP adapter. With<br />
this interface XPROG-m can access internal MCU EEPROM memory for<br />
reading and programming. Figure 2. and Table 1 shows ICP connector<br />

* In some cases requires 2K series resistor.<br />
** This signal is not required in Read mode. In<br />
Write mode this signal is required if EEPROM is<br />
programming protected. Dependence on target<br />
system the EEPROM is programming protected or<br />
not.<br />
