Pin Description
6071A–ATARM–28-Oct-04
Figure 12 on page 35 shows a test environment example. Test vectors are sent and inter-
preted 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.
