Abstract
A communication device includes a first device connected to a data line and a clock line and a second device configured to communicate with the first device via the data line and the clock line. A data signal transmitted to the second device from the first device via the data line swings between a first voltage and a second voltage, the second voltage has a voltage level higher than a voltage level of the first voltage, and a clock signal transmitted to the second device from the first device via the clock line is transited to a third voltage higher than the second voltage at a rising edge and then changed to the second voltage.
