Configuration dialog box as shown in Figure 4.17 .

Figure 4.17 Bus Analyzer Trigger Setup

Use the Triggers page to define a trigger in terms of one, two, three, or four events. For each term, define the read-write actions and clips.

These terms can be ranged or non-ranged triggers. For ranges, you can use A and B together, and C and D together (two different ranges), or you can use B and C together (one range).

You can edit the address masks and data masks for a “don’t care” qualifier on any address or data signal. For example, if you set a trigger for address 0x1000, but the corresponding mask is 0xFFFE, then either address 0x1000 or 0x1001 will trip the trigger.
