PURPOSE: A method and device for configuration of data processing system after reset are provided to accurately determine a reset vector address after reset, additional pin, nonvolatile storing position or data bus sampling. CONSTITUTION: A data processing system includes memories of various bit widths upon moving out of reset. A rest vector is composed of bytes, which are derived from a memory storing the reset vector in each memory operation. These bytes are stored in each possible memory structure in the prescribed manner, and a prescribed address is used to retrieve different bytes on a same part of data buses. A constituent value part of the retrieved reset vector is used to compose various parameters in the data processing system, so that parameters associated with other function characteristics in the memory or the system are initialized. A control part determines the manner in which a data part of the constituent value is adapted to various parameters in the data processing system.
