Abstract:
1. A slave electronic device, comprising: a capture unit, coupled to a host electronic device through a transmission lane, filtering out a high-frequency signal part from a control signal outputted by the host electronic device to generate a low-frequency control signal, wherein the control signal has a plurality of periods and the control signal respectively has a low-frequency signal part and the high-frequency signal part during odd periods of the plurality of periods and even periods of the plurality of periods; at least one low-speed unit, coupled to the capture unit, operating according to the low-frequency control signal; an embedded control unit, coupled to the transmission lane, communicating with the host electronic device using a predetermined communications protocol via the high-frequency signal part, wherein the capture unit further comprises: a unit buffer, obtaining the control signal from the transmission lane; and a low-pass filter, filtering out the high-frequency signal part from the control signal to generate the low-frequency control signal.
