• Software breaks cannot be set in read only areas, such as ROM. If an attempt is made to do so,
a verify error occurs at program startup (continuous execution in batch processing, step
execution, etc.).
• Always set a software break at the instruction start address. Setting a software break point in the
middle of an instruction, may cause a software error.
