Abstract
A data processing system () includes a CPU () and debug circuitry (). CPU () can execute instructions which provide direct input to one or more of trigger circuitry (), multi-function debug counters (), combining logic (), and action select and control logic (). Breakpoints can be cascaded, and separate breakpoint sequences can be triggered from a same trigger. A selected trigger () can produce a resulting action or trigger () but only if it occurs in a predetermined order compared to one or more other triggers (). Multi-function debug counters () can perform a wide variety of programmable functions, can be started and stopped using the same or separate triggers, and can be optionally concatenated with each other.
