Abstract

A processor begins exception processing in response to an exception event. Exception processing by the processor is halted during exception processing to facilitate debugging. The exception event can be a reset exception event or an interrupt exception event. Normal exception processing by the data processor can be resumed after debugging, or exception processing by the data processor can be aborted to allow the normal execution of instructions by the data processor to resume. An exception event can be selectively treated as an interrupt or a reset.
