15.5 WORKING WITH DEBUG FEATURES

When a debugger is selected in MPLAB IDE, several code debugging features are

available in the editor window.

•Filter Trace

• Breakpoints

15.5.1 Filter Trace

You may set up a simple filter trace in the editor window. However, the debug tool trace

feature must not be enabled to do this. Also, Filter-in and Filter-out trace are mutually

exclusive, i.e., setting one will clear the other.

Filter-In Trace

You may select (filter) the code that is traced into the trace buffer (for display in a Trace

window) by:

• selecting the code to add to the trace in the editor window

• right clicking in the window and selecting “Add Filter-in Trace” from the menu

Filter-Out Trace

You may select (filter) the code that is to be excluded from the trace buffer and thereby

trace only the unselected code into the trace buffer by:

• selecting the code to exclude from the trace in the editor window

• right clicking in the window and selecting “Add Filter-out Trace” from the menu

Removing Traces

To remove the code from the trace, right click in the filter code and select “Remove

Filter Trace”.

To remove multiple sections that have be used for trace, right click in the window and

select “Remove All Filter Traces”.

15.5.2 Breakpoints

Breakpoints stop executing code at a designated line so that you may observe register,

bit and variable values for debugging.

Breakpoints are a standard feature of MPLAB IDE Debug tools. For more information,

see Section 3.18 “Using Breakpoints”.
