Appendix

Applications Example

The following sequence gives an example of how one might

use the SCANPSC110F Bridge to perform 1149.1 operations

via a multi-drop scan backplane. The system involved has

10 card slots, 8 of which are filled with modules, and 2 slots

are empty. (See

Figure 18 ).

DS100327-17

Note: The value of the TMS during the rising edge of TCK is located next to each transition.
