Figure 13-2 shows a complete debug environment example. The SWJ-DP interface is used for standard
debugging functions, such as downloading code and single-stepping through the program and viewing core and
peripheral registers.

13.3.2 Test Environment
Figure 13-3 shows a test environment example (JTAG Boundary scan). 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.
