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.
