PROBLEM TO BE SOLVED: To easily realize low noise on a reception side of a wireless system without increasing the cost. SOLUTION: A microcontroller is provided to receive and process a demodulated signal generated by a receiving circuit on the reception side of the wireless system, and has a memory and a CPU. The memory stores a control program of the microcontroller. The control program of the microcontroller includes double loop routines for receiving standby operation comprising a 1st loop (large loop) and a 2nd loop (small loop) included in the 1st loop. The CPU has an instruction set comprising a plurality of instructions and executes the instructions according to the program stored in the memory. The CPU executes instructions (NOP instruction) having no relation with the receiving operation of the microcontroller in the 2nd loop repeatedly at least until noise due to repetition of the 2nd loop decreases below a desired level.
