When a breakpoint is hit, for both software and hardware breakpoints, a debug interrupt is generated and the debugger stops at the breakpoint address. The difference between them is how the debugger inserts the breakpoint at the required address. For the software breakpoints, the debugger modifies the program code.

Why we use breakpoints in debugging?

A breakpoint helps to speed up the debugging process in a large program by allowing the execution to continue up to a desired point before debugging begins. This is more efficient than stepping through the code on a line-by-line basis.
