摘要： A port securing module includes a power gate that is operable to be coupled in series to a power source and to a load. A resistor is coupled in parallel to the power gate. An operational amplifier includes an inverting input and a non-inverting input that couple the operational amplifier in parallel to each of the power gate and the resistor. The operational amplifier also includes an output that is operable to indicate whether a load is coupled to the power gate and, if a load is coupled to the power gate, supply a voltage to activate the power gate such that power is supplied to the load.

摘要： Polling of devices on an inter-IC (I.sup.2 C) is provided. An expansion processor resides on a primary I.sup.2 C bus. The expansion processor is coupled to a plurality of I.sup.2 C sub-buses each of which may host a plurality of I.sup.2 C devices. Data is transferred between the expansion processor and the plurality of I.sup.2 C devices via the corresponding sub-bus according to an I.sup.2 C protocol. Data transfer is in response to a request initiated by a bus master on the primary I.sup.2 C bus. The bus master communicates with a target device residing on one of the sub-buses by addressing the expansion processor. The bus master informs the expansion processor of the target device by sending the expansion processor a number of the sub-bus on which the target device resides, and an address of the target device. A data stream bound for the target device is directed to the expansion processor which then echos it to the target device. Likewise, a data stream bound from the target device to the bus master on the primary I.sup.2 C bus is transmitted to the expansion processor which then echos it to the bus master. Each of the target devices on the sub-bus can be polled to determine if they have failed. Failure of a device only affects operation of its sub-bus.
