  • Power saving device and electronic device using the same
    Patent number: 7454635
    Abstract: A microcomputer 11 stays in a power saving mode until a remote control signal is input and a first interrupt signal is input to an interrupt terminal 14. When the first interrupt signal is input, the microcomputer 11 performs an intermittent operation in which the power saving mode and the normal mode are periodically alternated with each other, and ends the intermittent operation when the remote control signal is received completely. After the intermittent operation, the microcomputer 11 stays in the normal mode if the remote control signal is a power-requesting signal and stays in the power saving mode otherwise.
