6.1
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. Four break conditions can be set in the PBC:
instruction fetch, data read, data write, and data read/write.
6.1.1
The PC break controller has the following features:
• Two break channels (A and B)
• The following can be set as break compare conditions:
• The timing of PC break exception handling after the occurrence of a break condition is as
• Module stop mode can be set
