This panel is used to display the results of disassembling the contents of the memory (disassembled text), and execute line assembly (see "2.6.4 Perform line assembly").
Furthermore, the instruction level debugging (see "2.8.3 Execute programs in steps") and the code coverage measurement result display [Simulator] (see "2.15 Measure Coverage [Simulator]") can be performed in this panel.
Up to a maximum of four of these panels can be opened. Each panel is identified by the names "Disassemble1", "Disassemble2", "Disassemble3" and "Disassemble4" on the titlebar.
The source text in the source file corresponding to the code data can also be displayed by setting to the Mixed display mode (default).
This panel appears only when connected to the debug tool.
A step execution is performed in instruction level units when the focus is in this panel (see "2.8.3 Execute programs in steps"). |
You can set the scroll range of the vertical scroll bar on this panel via the Scroll Range Settings dialog box which is opened by clicking the button from [View] on the toolbar. |
You can print the current screen image of this panel by selecting [Print...] from the [File] menu. |
This panel can be zoomed in and out by in the tool bar, or by moving the mouse wheel forward or backward while holding down the [Ctrl] key. |
This section describes the following.
The lines for which events can be set are shown with the background color in white (this mean that events cannot be set for those lines whose background color in gray).
In addition, the Event mark corresponding to an event that has been currently set is displayed.
This area is provided with the following functions.
By clicking where you want to set a breakpoint with the mouse, the breakpoint can be set easily.
The breakpoint is set to the instruction at the start address of the clicked line.
Once the breakpoint is set, the Event mark is displayed at the line that is set. In addition, the detailed information about the set breakpoint is reflected in the Events panel.
When this operation is performed at a place where any one of the event marks is already being displayed, that event is deleted and the setting of breakpoints cannot be done.
Note that the setting of events can be done only for those lines where the background color is shown in white.
See "2.9.3 Stop the program at the arbitrary position (breakpoint)" for details on how to set the breakpoint.
Event status can be changed from the following menu displayed by right-clicking the event mark.
Changes the selected event state to a Valid state. Event occurs when the specified condition is met. When the event mark ( ) which indicates that multiple events have been set is selected, all of the events that have been set are enabled. |
|
Changes the selected event state to an Invalid state. Event does not occur when the specified condition is met. When the event mark ( ) which indicates that multiple events have been set is selected, all of the events that have been set are disabled. |
|
When the event mark ( ) which indicates that multiple events have been set is selected, all of the events that have been set are deleted. |
|
Opens the Events panel to display the detailed information of the selected event. |
By hovering the mouse cursor over the Event mark, the name of the event, the detailed information for the event and the comments added to the event are pop-up displayed.
When multiple events have been set in the applicable place, information for each event, up to a maximum of three events, is listed and displayed.
The address per line to start disassembling is displayed (hexadecimal number notation fixing).
In addition, the current PC mark ( ) that corresponds to the current PC position (PC register value) is displayed.
The address width corresponds to the one in memory space of the specified microcontroller in the project.
For the source text line in the Mixed display mode, line numbers (xxx:) in the source file correspond to the start address are displayed.
The current PC mark changes from to when the position of the current PC is invalid (e.g., in cases where the current target core for debugging differs from the one selected at the time the program was stopped). |
This area is provided with the following functions.
By hovering the mouse cursor over a address or line number, the following information is pop-up displayed.
<Load module name> is displayed only when multiple load modules have been downloaded to the debug tool. |
The results of disassembling are displayed next to the corresponding source text as follows:
The highlighting color depends on the configuration in the [General - Font and Color] category of the Option dialog box. |
The source text can be set to non-display by clicking the button (toggle) on the toolbar or removing the check for [Mixed Display] from the context menu (this option is checked by default). |
Offset values are not displayed by default. They can be displayed by clicking the button on the toolbar or selecting [Show Offset] from the context menu. |
This area is provided with the following functions.
Instructions and code displayed in this panel can be edited (line assembly).
See "2.6.4 Perform line assembly" for details on how to operate it.
Execution can be controlled at the instruction level unit by step executing a program in a state where there is a focus on this panel.
See "2.8.3 Execute programs in steps" for details on how to operate it.
Various events can be set to the addresses/lines where the caret currently exists by selecting [Break Settings], [Trace Settings], [Timer Settings] or [Performance Measurement Settings] from the context menu.
The corresponding Event mark is displayed in the Event area when an event is set. In addition, the detailed information about the set event is reflected in the Events panel.
Note, however, that the setting of events can be done only for those lines where the background color is shown in white in the event area.
See the following for details on how to set events.
A breakpoint can be set or deleted easily in the Event area as well (see "(a) Setting/deleting breakpoints"). |
Variable names of C language, CPU registers, I/O registers, and assembler symbols can be registered in the Watch panel as watch-expressions.
See "2.10.6.1 Register a watch-expression" for details on how to operate it.
By clicking the button on the toolbar or selecting [Go to Symbol] from the context menu in a state where the caret has been moved to a instruction that has referenced a symbol, the caret position is moved to the address where the symbol at the caret position has been defined.
In addition, when following on this operation you click on the button on the toolbar or select [Back to Address] from the context menu, the caret position is returned to the instruction that has referenced a symbol before the caret was moved (the address value of the instruction that has referenced a symbol is displayed in Address).
Selecting [Jump to Source] from the context menu will open the Editor panel with the caret moved to the source line corresponding to the address at the current caret position (if the Editor panel is already open, the screen will jump to the panel).
In addition, similarly, selecting [Jump to Memory] will open the Memory panel (Memory1) with the caret moved to the memory value corresponding to the address at the current caret position (if the Memory panel (Memory1) is already open, the screen will jump to the panel).
When the coverage function is valid, lines corresponding to the specified coverage measurement area are shown highlighted based on the code coverage measurement result that is acquired by executing the program.
See "2.15 Measure Coverage [Simulator]" for details on the coverage measurement.
