I set the hardware breakpoint in the PD30, but when I execute the program with the breakpoint, the program stops after passing the

set breakpoint. What is the problem?

The emulator is monitoring the CPU bus during execution of the program. When the emulator detects the match condition of the

hardware breakevent, it generates a DBC interrupt to stop the program. It takes a few cycles for the CPU to receive the DBC

interrupt and stop the program, which is why the program is stopped a few cycles after the set breakpoint.
