4.10 Bus Analyzer
4–49 MMDS0508 Target Interface
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.)
