CHAPTER 2 DEPENDENCE FUNCTIONS
Notes:
• Hardware
There are the following considerations for the hardware break.
- Due to combination use with the sequencer or the trace trigger, the maximum setting number
varies.
- Do not set the hardware break to the instruction located in the delay slot. If such a setting is
performed, branching will not be performed in spite of re-execution after break.
- Make sure that the breakpoint must include the starting address of an instruction. Break may not
occur.
- When execution is performed starting from the address where the hardware break was set, if the
preceding execution has been stopped due to reasons other than instruction break, break will
occur without execution of the instruction. In such a case, when re-execution is performed, the
instruction will be executed.
•Software
There are the following considerations for the software break.
- Setting cannot be performed in areas, such as ROM, where write cannot be correctly performed.
In such cases, a verify error will occur when a program starts to be executed (when continuous
execution or step execution is started).
- Be sure to set the breakpoint in the starting address of an instruction. If the breakpoint is set in
the middle of an instruction, the program may run away.
