6.1
The user break controller (UBC) simplifies the debugging of user programs. Break conditions are
set in the UBC and a user break interrupt request is sent to the CPU in response to the contents of
a CPU or DMAC bus cycle. This function can implement an effective self-monitoring debugger,
enabling a program to be debugged by itself without using a large in-circuit emulator.

Figure 6.1 is the block diagram of the user break controller.
The following break conditions can be set:
When break conditions are met, a user break interrupt is generated. A user-created user break
interrupt exception routine can then be executed.
When a break is set to a CPU instruction fetch, the break occurs just before the fetched
instruction.
