To execute the
stepi
command

[Step Asm Inst] button
• Choose [Step Asm Inst] from the [Control] menu in the [Source] window.
• Enter [s] ([S]) 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
step
or
stepi
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
step
or
stepi
.
• Even with
stepi
,
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 status. The CPU exits standby status when an external interrupt is generated. Clicking the
[Stop] button also releases the CPU from standby mode.
