3.16 Stopping a Program when It Accesses Memory

To stop a program when it reads or writes a value to a global variable, set up a hardware break as described below.

Choose Event -> Hardware Break from the View menu to display the Hardware Break dialog box.

Open the OR page of the Hardware Break dialog box. In the Editor window, select a global variable that you want to be the

object of a hardware break so that a program is made to stop when it reads or writes a value to the variable, and drag-and-drop

the selected variable into the OR page.

Then click the Apply button.

When you run a program, it will stop running when a value is read or written to the global variable you have set.

Figure 3.28 Hardware Break dialog box

Notes: (1) Only the global variables that are 1 byte or 2 bytes in size can be set.

(2) Local variables cannot be set.
