Setting the IO Port Access Breakpoint

To set a breakpoint for intercepting the IO port access event:

1. Halt the target by pressing the Suspend button.

2. In the Breakpoints view, click the Add Breakpoint button.

3. In the opened dialog box, select the IO Breakpoint radio button and specify the breakpoint address.

   Note:

   You can enter the address in a non-hex format and it will be automatically converted into the hex equivalent.

1. Click OK.

Now you can resume you target and see how the specified event is caught. When (or if) the breakpoint is hit, the target gets halted.

You can also view and edit IO port values using a scripting solution.
