In computer systems deliberate initializations/resets of the processor latches which represent the internal processor states are necessary to erase only such information which is not required for a subsequent operation, e.g., processing/logging error data, prior to a processor start. One or more reset areas are defined which are initialized/reset in a staggered mode, where in each area a group of latches is assembled which have to be initialized/reset depending on the cause, e.g., power-on, for such a system initialization/reset. The latches within a reset area are connected to form shift registers which are initialized/reset by propagating a binary zero through all latches of the area(s) to be reset.
