ABSTRACT:
A method and apparatus for providing notice of impending initialization prior to initializing a microprocessor to enable the microprocessor to store operating data prior to initialization and to use the stored operating data after initialization. The apparatus includes a first means for supplying a first signal to warn the microprocessor of an impending initialization and a second means for supplying a second signal to cause the initialization of the microprocessor. In response to the first signal, the microprocessor is programmed to recognize that an initialization of the processor is scheduled to occur and therefore operates to complete current program tasks and initiates the storage of a selected set of operating data within a memory storage device. In response to the second signal, the microprocessor is initialized and operates to detect whether the initialization of the microprocessor corrupted any of the selected operating data stored within the memory storage device. If the microprocessor finds that the stored operating data is valid, the microprocessor begins operations using the stored operating data. The second signal also synchronously resets the first means and the second means upon the initialization of the microprocessor.
