Abstract:
1. A device comprising: a programmable event engine for executing an event thread and further for detecting events in accordance with a plurality of programmable states of said event thread; a memory coupled to said event engine and for storing said plurality of programmable states of said event thread, wherein said plurality of programmable states are for re-configuring said event engine in response to detecting one of said events during execution of said event thread, and wherein said re-configuring said event engine comprises changing at least one condition used by said event engine to detect said events; and wherein said event engine is further for monitoring a first signal on a first external pin, wherein said event engine is further operable to detect a first event in accordance with a first programmable state of said plurality of programmable states, wherein said event engine is further operable to change from operation in accordance with the first programmable state to operation in accordance with a second programmable state of said plurality of programmable states in response to detecting the first event, wherein said event engine is configured to change from operation in accordance with the first programmable state to operation in accordance with a second programmable state by loading data from the memory, wherein said event engine is further operable to detect a second event when operating in accordance the second programmable state, and wherein said event engine is further operable to detect said first and second events contemporaneously with said execution of said event thread, and wherein said event engine is further operable to generate an output signal in response to detection of said first event.
