Remote control reception circuit
专利汇可以提供Remote control reception circuit专利检索，专利查询，专利分析的服务。并且PURPOSE: To simplify the software processing for discriminating a remote control signal and to reduce the number of steps of the program by adding a reader detection circuit, a data discrimination circuit, and a trailer detection circuit and giving each output as an interrupt signal to a CPU.
CONSTITUTION: The circuit is provided with a reader detection circuit 6 for a remote control signal, a data discrimination circuit 7, and a trailer detection circuit 8 and the output signal of the circuits 6-8 is given to a CPU 3 of a microcomputer as an interrupt signal. When the remote control signal is inputted to the microcomputer, a remote control reception interrupt signal is generated from an edge detection circuit 1 and the CPU 3 processes a remote control signal decoding processing routine and processes sequentially each interrupt signal from the reader detection circuit 6 for a remote control signal, the data discrimination circuit 7, and the trailer detection circuit 8 to apply decoding processing of a series of remote control signals. Thus, it is not required to process complicated software processing and the number of program steps is decreased.
