4.10.4 RTA Control Panel Settings for Use with the Execution Graph
The TRC module allows you to control what events are recorded in the
Execution Graph at any given time during the application execution. The
recording of SWI, PRD, and CLK events in the Execution Graph can be
controlled from the host (using the RTA Control Panel as shown in Figure 4-23;
DSP/BIOS
→ RTA Control Panel in Code Composer Studio software) or from
the target code (through the TRC_enable and TRC_disable APIs). See section
3.3.4.2, Control of Implicit Instrumentation, page 3-16, for details on how to
control implicit instrumentation.

When using the Execution Graph, turning off automatic polling stops the log
from scrolling frequently and gives you time to examine the graph. You can
use either of these methods to turn off automatic polling:
❏ Right-click on the Execution Graph and choose Pause from the shortcut
menu.
❏ Right-click on the RTA Control Panel and choose Property Page. Set the
Event Log/Execution Graph refresh rate to 0. Click OK.
You can poll log data from the target whenever you want to update the graph
by right-clicking on the Execution Graph and choose Refresh Window from
the shortcut menu. You can choose Refresh Window several times to see
additional data. The shortcut menu you see when you right-click on the graph
also allows you to clear the previous data shown on the graph.
