Abstract
A remote control receiving circuit for receiving a remote control signal from a transmitter includes a header interrupt generation circuit that outputs a header interrupt signal when detecting the header of the signal, a data interrupt generation circuit that outputs a data interrupt signal when the header has been detected and the predetermined data receiving is completed, and a switch that selects the header interrupt signal or data interrupt signal in accordance with an instruction of the CPU. A CPU has one interrupt port for receiving the interrupt signal selected by the switch, and performs control in accordance with the received interrupt signal. Therefore, a remote control receiving system can reduce the codes, processing power, and resources of the CPU, which are used to implement the remote control signal receiving function, and reduce the cost of the entire system.
