PROBLEM TO BE SOLVED: To provide a semiconductor IC circuit which accomplishes a BIST(built in self test), whitout having to provide an exclusive test terminal. SOLUTION: The semiconductor IC circuit is provided with a CPU 11 (central processing unit) to execute a prescribed program, a memory 12 to store the program, data and the like, a logic circuit 13 which performs logic operations, a BIST circuit 14 which performs BIST, a reset terminal 15 to receive a reset signal from the outside, a clock terminal 16 to receive a clock signal from the outside, and an output terminal 17 to output a signal to the outside. The BIST circuit 14 receives the reset signal from outside through the reset terminal 15, and the operation thereof is controlled by the reset signal.
