Abstract
In an information transmission system, a first frequency dividing section divides a clock signal by 2X, where X is information to be transmitted, and a second frequency dividing section divides an inverted clock by 2Y, where Y is information to be transmitted. The exclusive-OR of the outputs of the first and second frequency dividing sections is output to a frequency divisor detection section, which measures the time interval between changes thereof at the rising edge of the clock and the falling edge of the clock, thereby reading the set values of the first and second frequency dividing sections via a data signal line.
