Software Break
It is a function to bury the instruction for the break under the memory, and to do the break by the instruction
execution. The break is done before an instruction the specified address is executed.
The number that can be set is 16 points.
When a break occurs due to a software break, the following message is displayed on the status bar:
Break at Address by breakpoint
■
Setting Method
The software break is controlled by the following method.
• Command
- SET BREAK/SOFT
Refer to "3.1 SET BREAK (type 1)" in "SOFTUNE Workbench Command Reference Manual".
• Dialog
- Breakpoint Set Dialog [Code] tab
Refer to "4.6.4 Breakpoint" in "SOFTUNE Workbench Operation Manual".
• Window
- Source window/Disassembly window
Note:
There are a couple of points to note when using software breaks.
• Software breaks cannot be set in an area that cannot be written, such as ROM. If attempted, a
verify error occurs at starting the program (when continuous execution, step execution, etc.,
started).
• Always set a software break at the instruction starting address. If a software break is set in the
middle of an instruction, it may cause a program null-function.
