Advanced Features
The approximate trigger cycle will be highlighted in blue and will be numbered
as cycle 0. All other cycles will be numbered based on this cycle. Cycles that
occurred before the trigger point will have a negative cycle number and cycles
that occurred after the trigger point will have a positive number. If the trace
buffer was displayed after a user halt, a software break point, or a complex
trigger that halted the processor, the trigger point will be the last traced cycle.
If a complex trigger filled the trace buffer without halting the processor, the
trigger point will show the approximate cycle when the complex trigger fired.
The menu items in the window perform the following functions:
• File>Save – Saves the displayed trace buffer information to a tab
delimited file.
• Data>Find Trigger – Brings the trigger point to the center of the
displayed cycles.
• Data>Reload – Reloads the trace information from the emulator.
• Options>Configure – Brings up the Configure Trace dialog, described in
Section 6.5.2.
• Options>Reset Time Stamp – Resets the value of the time stamp.
• Help – Brings up the on-line help for Trace Memory.
Select Data>Reload to force an upload of what ever data has currently been
collected by the trace buffer. This allows you to see where your program is
executing. This is often useful if your trigger is never reached.
Note: Source and destination data addresses and values are not
available when using processor modules based on the 12-bit
PICmicro core (PIC16C5X and related parts).
