Trigger Module Settings Window
This window can be opened from context sensitive context menus in the Source, Data,
Memory and Assembly component windows, from the Connection menu and also when
clicking on a Status Bar displayed mode (Automatic, by default).
The on-chip DBG module can be fully controlled from within this window.
The dialog is designed with three tabs. Trigger Settings is the main tab, where all modes of
the debugger can be selected in the top drop down box.

Trigger Module Usage/DBG Module Setup
In the Trigger Settings main tab, three modes can be selected to take advantage of the on-
chip DBG module:
• An Automatic mode, which does not provide trigger functionalities, therefore, does
not provide complex breakpoints or complex watchpoints, but typically, four
hardware breakpoints and one watchpoints that can be set as usually via windows
context sensitive context menus or command line commands.
• An Expert mode, which is a “Do It Yourself” interface to set the on-chip DBG
module. In that case, the debugger does not use any on-chip module resources. Refer
to silicon specifications to correctly set up the DBG module. The debugger still
provides the Trace rebuild window and support to display, when available, the results
of the captured data.
