6.16.4 Function Calls
This mechanism is used to only collect trace information on the function calls.
(1) Make the setting such that a break occurs at the address on the line that has ‘p_sam->s0=a[0];’ within the
tutorial function (H’00001082 in this example) (for details on this, refer to section 6.15.1, Software
Break Function).
(2) Select [Reset Go] from the [Debug] menu. Processing stops when the break condition is satisfied, and the
[Trace] window then displays trace information.
(3) Select [Function Call…] from the popup menu displayed by clicking the right-hand mouse button on the
[Trace] window. The [Function Call Display] dialog box will be displayed.

(4) Click the [Enable] radio button and then the [OK] button. Only the information on function calls is now
displayed in the [Trace] window (the [Label] column’s right-side boundary has been moved to the left in the
[Trace] window to show the function calls).

(5) To return the display in the [Trace] window to its previous state, follow the procedure in (3) to display the
[Function Call Display] dialog box. Click the [Disable] button and then the [OK] button.
(6) Remove the event points that have been set and clear the trace information. Clicking the right-hand mouse
button on the [Breakpoints] window displays a popup menu. Select [Delete All] from this menu to remove
all the event points that have been set. Clicking the right-hand mouse button on the [Trace] window displays
a further popup menu. Select [Clear] from this menu to clear the trace information.
