10.4 Application Examples
10.4.1 Debug Environment
Figure 10-2 shows a complete debug environment example. The ICE/JTAG interface is used for standard
debugging functions, such as downloading code and single-stepping through the program. A software debugger
running on a personal computer provides the user interface for configuring a Trace Port interface utilizing the
ICE/JTAG interface.

10.4.2 Test Environment
Figure 10-3 shows a test environment example. Test vectors are sent and interpreted by the tester. In this
example, the “board in test” is designed using a number of JTAG-compliant devices. These devices can be
connected to form a single scan chain.
