ABSTRACT:
A method for performing data communication between two circuits is provided. The method comprises the steps of: serially transmitting information between two circuits, determining a first level change in one direction of a pulse signal output from one of the circuits to the other as a reference time, judging whether a first data bit is "1" or "0" in accordance with a time period from the reference time to a second level change in the one direction following the reference time, and determining the second level change in the one direction as the reference time relative to the next bit of data in the pulse signal, whereby data of a predetermined number of bits are continuously transmitted.
