FIGURE 4-14: SET BREAKPOINTS DIALOG

The additional breakpoint will appear below the previous breakpoint in the Break-

points dialog and also as a breakpoint symbol next to the following line of code:

PORTA = counter; //display on port LEDs

The breakpoint symbol is yellow in this case because it was set based on an

address.

3. Run the program to see it halt at the first breakpoint. The values in the Watch win-

dow will not change. Then run again to see it stop at the second breakpoint. (The

program may skid past this breakpoint.) Now the values in the Watch window will

change.
