  • Publication number: 20120083212
    Abstract: A data transmitting system, comprising: a processor; a first transmitting interface; a first transmitting apparatus; a second transmitting interface; a second transmitting apparatus and a signal transmitting line. The processor enters a power down mode when the first transmitting apparatus does not output data. The first transmitting generates a data transmitting indication signal when the processor is operated in the power down mode and the first transmitting apparatus has data to be output. The second transmitting apparatus generates a recovery signal according to the data transmitting indication signal, and transmits the recovery signal to the processor via the second transmitting interface. Thereby the processor goes back to a normal mode to control the first transmitting apparatus to output data.
