CHAPTER 16: DEBUGGER
Operation

3. Disassemble display (selected by [Unassemble] button or u command)
In this mode, the window displays the addresses, codes, disassembled contents and extended instruction
codes. This format is selected when the db33 starts up.
Display of source line numbers and source statements
The source line numbers and source statements can only be displayed when the srf33 object file including
debug information for source display is loaded. Furthermore, the source statements that are actually
displayed from this file are those which have had the -g option specified by the C compiler or preprocessor.
The db33 displays the source lines corresponding to the address of each code and the source statements
bearing information on the source lines up to the immediately preceding code. Therefore, uncoded source
statements written after the end of code are not displayed.
Display of the current PC
The black underline indicates that the line will be executed next (the line of the current PC address). In the
mixed display and disassemble display modes, the entire line is underlined. In the source display mode, the
entire line is underlined only when the current PC falls upon the address of the first instruction in the source.
Otherwise, the address part is not underlined.
Display of breakpoints
The "!" displayed immediately before or after an address indicates that the address is a breakpoint. The "!"
displayed immediately before an address indicates a software break and the "!" displayed immediately after
an address indicates a hardware break. Furthermore, the line set as a breakpoint is underlined in red.
If a breakpoint is set somewhere other than the first instruction address displayed in the source display
mode, it is marked with "?" and a blue underline in place of "!" and a red underline.
Display of unused areas
The unmapped areas in the memory specified by a parameter file are marked with words "no map".
Others
If no source code corresponding to the address is loaded in the mixed display mode, "no source" is
displayed in the source part.
Opening and closing the window
When db33 starts, the [Source] window opens at the same position in the same size as when the debugger
was last terminated. However, if the -w option is specified, this window is not opened automatically.
The [Source] window can be opened by using the [Source] command on the [Window] menu or can be
closed by clicking on the close box.
