5.9.9 Filtering Trace Information
Use the filter function to extract only the necessary records from the acquired trace information. The filter function filters the
trace information in software that was acquired by hardware.
Unlike the “Capture/Do not Capture conditions” where you set acquisition conditions before getting trace information, this
function permits you to change filter settings for the acquired trace information any number of times.
Therefore, the necessary information can be extracted easily, with data analysis significantly facilitated.
The filter function does not affect the trace memory, so that its content remains intact.
The filter can be used when the selected trace mode is Fill until stop, Fill until full or Fill around TP and the selected display
mode is Bus or Disassembled.
(1) Auto-filter function
To use the filter function, choose Auto Filter from the context menu of the Trace window. When Auto Filter is turned on, each
column of the Trace window is marked with an auto-filter arrow [ ].
Click any arrow [ ] and select the necessary condition from the ensuing drop-down list. That way, you can easily filter the
records to get those that meet the condition. Selecting Option in the drop-down list brings up the Option dialog box. In this
dialog box, you can set detail conditions.
Some columns such as Address and Data have only Option provided in the drop-down list because they do not have other
inherent items. Selecting All returns you to a non-filter state.

If after filtering records in bus display mode you switch to disassemble-only or source-only display, Auto Filter is deselected.
Similarly, when after filtering records in disassembled display mode you switch to bus-only or source-only display, Auto Filter
is deselected.
