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
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.
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.
