Abstract
PURPOSE:To connect the same number of signal lines to gather data independently of the quantity of data reception parts by divisionally assigning the clock pulse train from a transmission part to respective reception parts and controlling the level value of a prescribed bit of this clock pulse in accordance with gathered input data. CONSTITUTION:A transmission part 101 is provided with a clock generating circuit 103 which sends a clock pulse 120, a frequency converting circuit 104 which receives the clock pulse 120 to change of the clock frequency, and a comparing circuit 105 which compares an output signal 124 of the frequency converting circuit 104 and a data gathering signal 123. When the clock pulse 120 or data gathering signals 121 and 122 are received, frequencies of the clock pulse in time zones determined in reception parts 102, 110, and 111 are converted to preliminarily determined frequencies and a prescribed bit of the clock pulse is inhibited in accordance with gathered data input to gather data. Consequently, data in reception parts is gathered by one transmission signal line and one reception signal line.
