5.9.9 Filtering Trace Information
Use the filtering facility to extract only the records you need from the acquired trace information. This facility is achieved by
software filtering of the trace information that has been acquired by hardware.
Unlike “Capture/Do not Capture”, where the conditions must be set before getting the trace information, the filter settings can
be changed any number of times. This makes it easy to extract required information, significantly facilitating data analysis.
Filtering does not affect the trace memory, so that its contents remain intact.
Filtering is available when the selected trace mode is Fill until stop, Fill until full or Fill around TP and the selected display
mode is bus or disassembly.
(1) Auto-filtering
To use the filtering facility, choose Auto Filter from the popup menu of the Trace window. When Auto Filter is turned on, each
of the columns in the Trace window is marked with an auto-filter arrow [ ].
By simply clicking on the arrows [ ] and selecting desired conditions from the drop-down lists, you can filter the records to
get those that meet the conditions. Selecting Option in the drop-down list brings up the Option dialog box. In this dialog box,
you can set detailed conditions.
Items such as Address and Data do not have a manageably small fixed set of items, so the only entry in the drop-down list for
these columns is Option… Selecting All returns the window to the non-filtered state.

If you switch the display mode to disassembly or source after filtering records in bus mode, Auto Filter is deselected. Similarly,
if you switch the display mode to bus or source after filtering records in disassembly mode, Auto Filter is deselected.
