By registering C language variables, CPU register, SFR, and assembler symbols to the Watch panel as watch-expressions, you can always retrieve their values from the debug tool and monitor the values in batch.
The values of watch-expressions can be updated during the program is in execution (see "2.10.6.7 Display/modify the contents of watch-expressions during program execution").
Select the [View] menu >> [Watch] >> [Watch1 - 4] to open the Watch panel.
The Watch panel can be opened up to 4 panels. Each panel is identified by the names "Watch1", "Watch2", "Watch3" and "Watch4" on the titlebar, and the watch-expressions can be registered/deleted/moved individually, and they are saved as the user information of the project.
For details on the contents and function in each area, see the section for the Watch panel.
