Abstract
For some data processing systems, it is important to be able to handle overlapping debug events generated by a shared set of debug resources which are trying to cause both exception processing and debug mode entry. However, exception processing and debug mode entry generally have conflicting requirements. In one embodiment, exception priority processing is initially given to the software debug event. Normal state saving is performed and the first instruction of the debug exception handler is fetched, but not executed. Priority is then switched from the software debug event to the hardware debug event and a debug halted state is entered. Once processing of the hardware debug event has been completed, priority is returned to the software debug event and the debug exception handler is executed.
