The measurement result indicates, for example, whether the relevant line of the second slot 2600 has a short circuit or an open circuit, but is not limited thereto.

In addition, the processing unit 1600 can make a more detailed determination according to the received feedback signal. In one embodiment, the processing unit 1600 further determines whether the change in the voltage level on the associated pin is within a tolerable range or standard to determine whether the associated line is abnormal. For example, the processing unit 1600 can determine whether the voltage level on the relevant pin is greater than a predetermined upper limit or less than a predetermined lower limit. Alternatively, the processing unit 1600 can determine whether the voltage level on the associated pin is pulled back to the desired voltage level for a predetermined time. Alternatively, the processing unit 1600 can determine whether the average voltage on the associated pin for a predetermined time meets the requirements. In fact, corresponding to the type of signal received by the second slot 2600, such as a pulse width modulation signal or a DC voltage signal, the processing unit 1600 can perform a corresponding analysis determination. The above is merely an example, and it is not limited herein how the processing unit 1600 determines based on the voltage level on the associated pin.
