Microcontrollers Debugger Manual

Watchpoints

Watchpoints are control points associated with a memory range. Program execution stops

when the memory range defined by the watchpoint has been accessed. The debugger

supports different types of watchpoints:

• Read Access Watchpoints, which are activated when a read access occurs inside the

specified memory range.

• Write Access Watchpoints, which are activated when a write access occurs inside the

specified memory range.

• Read/Write Access Watchpoints, activated when a read or write access occurs inside

the specified memory range.

• Counting Watchpoints, activated after a specified number of accesses occur inside

the memory range.

• Conditional Watchpoints, activated when an access occurs inside the memory range

and a given condition is TRUE.

Watchpoints are controlled through the Controlpoints Configuration Window

(Watchpoints Tab). This window can be opened through the Memory or Data component

window context menu, as described below:

To open the Controlpoints Configuration window with the Watchpoints tab exposed:

1. Position your cursor in either the Memory or Data component window.

2. Press the right mouse button.

3. Select Show Watchpoints from either menu.

4. Click the left mouse button.

The ControlPoints Configuration window appears. The Watchpoints tab of this window is

shown in Figure 4.6
