    摘要: A data processing apparatus which saves data in a volatile memory into a nonvolatile memory when power is off, the data processing apparatus including: a detecting circuit for outputting a momentary interruption detecting signal when a power source voltage is below a first threshold voltage, and a power failure detecting signal when the power source voltage is below a second threshold voltage that is lower than the first threshold voltage; and a control section adapted to start saving of the data in the volatile memory into the nonvolatile memory when the detecting circuit has output the momentary interruption detecting signal, continue save of the data, and carry out a predetermined shutdown processing when the detecting circuit has output the power failure detecting signal after the detecting circuit has output the momentary interruption detecting signal.

    摘要: To provide a system capable of avoiding an apparatus anomaly such as a system hang, even when an anomaly condition of connection in the cable connecting the apparatuses occurs. A first apparatus 10 in the transmission side includes: a data processing device 12; a buffer register 22 in which the processing device writes the data to be sent; a transmission section 23 for sending the data stored in the buffer register to a second apparatus 40 connected by a cable 3; and a loop detection section 27 for detecting an anomaly condition of connection in the cable during the data transmission. When detecting the anomaly condition of connection in the loop detection section, the first apparatus clears the buffer register to release the processing device from the data writing waiting, and at the same time the first apparatus notifies the processing device of the occurrence of the anomaly condition.
