This is for profiling. You are not interested in doing that.
[quote user="yanzhen fu"]how can i use soft-breakpoint , ? I heard before ,but never used .[/quote]
A software breakpoint will halt the target. You don't want to do that
You want to use a WATCHPOINT. That will monitor the bus for activity non-intusively. You can watch the program counter for specific address and when that address is reached (basically "watch" the value of the program counter), you can trigger it to do something besides halt.
Also you can do what Patrick suggests.
Thanks
