4.10.2.2.1 Term

Use this area to specify the term displayed for editing. The term identifies an event; that is, an event is a frame that satisfies the term.

4.10.2.2.2 Address

In this edit box, specify the address to which the system writes data or from which the system reads data.

4.10.2.2.3 Data

In this edit box, specify the data that the system is to read or write.

4.10.2.2.4 Strobes

4.10.2.2.5 Group A & B Clips

Use this area’s toggle controls to specify each logic clip as High, Low, or Don’t Care. The clips buttons show the Group A logic clips with their respective colors.

You use logic clips to trace the signals of your target system as it runs under software control. When a trigger occurs, a breakpoint shows you the states of significant logic signals before, at, and after the trigger.

To specify term triggering outside, not inside, a defined range, check the Invert checkbox.

To clear all the changes in the Bus Analyzer Configuration dialog box, click the Clear button.

To save your trigger settings and close the dialog box, click the OK button.

4.10.2.3 Sequencer Setup

To choose the recording mode, select the menu item Trace>Setup... to open the Bus Analyzer Configuration dialog box as shown in Figure 4.18. Then click on the Sequencer tab (see the figure below).

In non-triggered (continuous and counted) modes, data collection continues until you stop the analyzer.
