Abstract
An LSI system is disclosed in which a plurality of status registers for indicating the internal status of the system are connected to each other so as to form a hierarchical structure and the contents of each of the remaining status registers other than one status register can be transferred to an output register through a bus, to make it possible to provide additional status registers in the system without increasing the number of address signals used and the number of pins connected to external address signal lines.
