Zusammenfassung:The last value of an element of a computing system is continually stored within a first register. The element is cleared during any restart or reset of the computing system. The last value is relevant to debugging of the computing system when the computing system fails to perform as expected and/or as desired. Upon receiving an instruction to reset the computing system via a first reset signal corresponding to pressing of a reset button or a second reset signal corresponding to a baseboard management controller issuing a reset command, the last value of the element as stored within the first register is copied to a second register. The computing system is then reset. The last value of the element as stored within the second register persists within the second register during this type of reset, but is cleared during any other reset or restart of the computing system.
