Abstract
The present invention discloses an electronic device using pulse density modulation for communication, comprising: a pulse density modulation interface; a first circuit to output a clock signal and a data signal through the pulse density modulation interface; and a second circuit to receive the clock and data signals and thereby determine whether the level change times of the data signal reach a predetermined threshold while the clock signal remains unchanged, so as to verify whether the clock and data signals satisfy a start protocol. In an embodiment of the present invention, the above-mentioned predetermined threshold is equal to or more than three.
