Debug Interface
5-14
The EmbeddedICE Logic comprises:
•
•
•
The debug control register and the debug status register provide overall control of
EmbeddedICE operation.
You can program one or both watchpoint units to halt the execution of instructions by
the core. Execution halts when the values programmed into EmbeddedICE match the
values currently appearing on the address bus, data bus, and various control signals.
You can mask any bit so that its value does not affect the comparison.
You can configure each watchpoint unit for either a watchpoint or a breakpoint.
Watchpoints and breakpoints can be data-dependent.
