Data Sheet
7
On Chip Debug Support (OCDS) is implemented to provide the most important hardware
emulation features without special emulation chips at minimum cost.
Note: For more detailed information please refer to ’OCDS C166CBC Target
Features of OCDS:
• Hardware, software and external pin breakpoints (BRKIN, BRKOUT)
• Up to 4 instruction pointer breakpoints
• Masked comparisons for hardware breakpoints
• Independent modules for OCDS and debug port (interface to external debugger)
• The OCDS can also be configured by a monitor
• Trace support in conjunction with the debug port
• Support of multi CPU systems
• Single stepping with monitor or CPU halt
Basically, debug operations are controlled with debug events and event actions:

The application of OCDS is to debug the user software running on the CPU in the cus-
tomer’s system. This is done with an external debugger, that controls the OCDS via the
independent debug port.
An standard (IEEE 1149.1) JTAG interface can be used as independent port to the
OCDS within C166CBC systems.
Via the JTAG interface and the integrateds modulle called
hardware can access the OCDS registers and arbitrary memory locations with the new
DPEC mechanism. DPEC transfers are PEC transfers, executed by the core CPU, but
controlled by the Cerberus. With DPEC transfers, injected into the CPU’s pipeline or ex-
ecuted in CPU-Hold state, data exchange can be executed by the Cerberus module with-
in the whole address space, including all SFRs and dual-port RAM as well as program
or data Flash modules on chip (for example).
