GUI
The next and nexti commands can also be executed using one of the methods below. In such case, however,
you cannot specify the number of steps to execute. (Only one step of the program is executed.)
To execute the next command
• Click the [Next] button in the [Source] window.
[Next] button
• Choose [Next] from the [Control] menu in the [Source] window.
• Enter [n] ([N]) while the [Source] window is open and displayed in SOURCE mode.
When the program is single-stepped using the method above, information about the line executed appears in
the [Console] window and is also output to a log file at log output.
To execute the nexti command
• Click the [Next Asm Inst] button in the [Source] window.
[Next Asm Inst] button
• Choose [Next Asm Inst] from the [Control] menu in the [Source] window.
• Enter [n] ([N]) while the [Source] window is open and displayed in other than SOURCE mode.
When the program is single-stepped using the method above, information about the line executed appears in
the [Console] window and is also output to a log file at log output.
While the next or nexti command executes the target program, the contents displayed in the [Source] and
[Registers] windows are updated each time one step is executed. The [Memory] window is not updated.
Notes
• The program cannot be single-stepped from an address that does not have source information (i.e., debugging
information included in the object). The program can be run continuously, however, by using the continue
command.
• To run the program from the beginning, execute c17 rst (reset) before next or nexti.
• Even with nexti, ext-based extended instructions are executed collectively (i.e., entire extended
instruction set consisting of two or three instructions) as one step.
• Interrupts are accepted even while single-stepping the program.
Similarly, the halt and slp instructions are executed while single-stepping the program, causing the CPU
to enter standby mode. The CPU exits standby mode when an external interrupt is generated. Clicking the
[Stop] button also releases the CPU from standby mode.
