Figure 11-2 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 pro-
gram and viewing core and peripheral registers.

11.3.2 Test Environment
Figure 11-3 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.
