The PC break controller (PBC) provides functions that simplify program debugging. Using these
functions, it is easy to create a self-monitoring debugger, enabling programs to be debugged with
the chip alone, without using an in-circuit emulator. A block diagram of the PC break controller is
shown in figure 6.1.
