4.10 Bus Analyzer

4.10.4.3.2 Address

This column lists frame address bus values, as four hexadecimal digits. Each value is the address on the address bus at the time the analyzer strobed the frame into the trace buffer.

4.10.4.3.3 Data

This column lists frame data bus values, as two hexadecimal digits. Each value is the values on the data bus at the time the analyzer strobed the frame into the trace buffer.

4.10.4.3.4 Time Tag

This column lists representations of the time tag count, stored when the analyzer strobed each frame into the trace buffer. If the time tag clock was the bus clock, this column shows the number of time-tag-clock cycles. If the time tag clock was a different clock, this column shows a number of seconds (or fractions of seconds).

4.10.4.3.5 Time Measuring

To assign the time-tag value 0 to a frame, position your mouse cursor over the frame entry and click the right mouse button. The Trace menu appears; select Set Time Base. The analyzer re-displays all time-tag values relative to the bus cycle of the frame you specified.

4.10.4.3.6 Control Signals

The remaining columns of the Trace dialog box show the values of control signals or of logic clips.

4.10.4.4 Instructions Only Display

If you choose the Instructions format, the software displays only the frames where instructions start as show in Figure 4.21. (The Instructions format is not available for an Events Only recording mode.)
