ICC connection requirements

To take advantage of ICC, you must integrate an ICC connector into your application

hardware when you start developing your application. To help you implement ICP and ICD in

the development of your application, this section provides a summary of points you should

consider when installing an ICC connector.

Figure 24.

In-circuit communication connector

Using the ICC protocol requires that a minimum of 4 and as many as 6 pins of your ST7 be

relayed to the ICC connector. These connection requirements are illustrated in Figure 25,

below and summarized in Figure 4.

and USB ports

To connect to your application board for ICP and ICD, you

need to install a 10-pin, HE-10 type connector (also called

an ICC connector) and ensure the appropriate

connections to your ST7. This connector receives the ICC

cable and relays the signals required for ICP and ICD to

your ST7.
