Setting Hardware Breakpoints [closed]

开发者_如何转开发 It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 11 years ago.

I'd like to understand how HBP's works,

Can you tell me how to set hardware breakpoints using assembly?

Which kind of hardware breakpoint do you mean? There are the type set with 80x86 debug registers. There are micro controllers with a JTAG interface which allow full speed execution and hardware breakpoints. And there is the breakpoint possible with dedicated external hardware, most often an In-Circuit Emulator or ICE.

Each has a specific mechanism for setting up a breakpoint. The links I provided should get you started.
