A device for generating a pulse signal includes at least one first register which stores waveform data therein, a pulse signal generation unit which generates a pulse signal in accordance with the waveform data of the first register, a control unit which is connected to a bus, and is controlled by control signals supplied from the bus, and a signal line which is separate from and independent of the bus, and is connected to the control unit, wherein the control unit updates the waveform data of the first register in response to a signal that is externally supplied through the signal line.
