PURPOSE: To provide the hysteresis characteristic state control system in which the number of components is reduced and the processing time is decreased.

CONSTITUTION: The system is made up of a hysteresis state control table memory 3 storing table reference information, a table reference high-order address register 5 storing preceding table selection information, and a table reference low-order address register 6 storing state detection information detected this time, and also made up of a table reference address register 4 generating address data used to designate an address in which table selection information is set to high-order bits and state detection information is set to low-order bits, an information latch/output register 7 consisting of a table selection information latch register 8 latching the table selection information comprising high-order bits of the table reference information and a state control register 9 giving the state control information comprising low-order bits to a state controlled unit 2, and up of a main control section 1 controlling input/output of each information between system elements.
