PURPOSE:To enable a signal not allowed for generation of any distortion to be sent through multiplexing by adding a circuit fetching a timing of the sending a signal externally multiplexedly into a chip of gate array configuration. CONSTITUTION:A frame counter section 13 generating a sample timing signal of a transmission signal is provided at the waveform transfer mode where the timing to sample a transmission signal is generated in a gate array. Then an external sampling timing signal detection section 16 is provided, which detects an external sample timing signal at the command transfer mode giving the timing sampling the transmission signal externally, generates the reset signal of a system clock generating section 11 and resets a serial/parallel conversion section 14 outputs the transmission data serially. Thus, the signal not allowed for generation of any distortion is multiplexed and sent. |
