The present invention provides a system and method, operable in a multi-context processor, for allowing a current context to change an event sensitivity of a future context. In one embodiment, the system includes a context control register, accessible to the current context, for receiving event mask data defining the event sensitivity of the future context. The system further includes a context controller, associated with the context control register and invokable from within the current context, that causes the event mask data to be employed in defining a content of an event mask register of the future context.
