Data communication method between circuits |
摘要 |
A method is disclosed for performing data communication between a pair of circuits. The data communication is established by serially transmitting information which includes pulse signals. In executing the method, a reference time is determined as an instant of a first level change in a first direction of a pulse signal output from one of the circuits to the other. A judgement is made as to whether a first bit of data is a "1" or a "0" in accordance with a time period extending from the reference time to an instant of a subsequent level change in the first direction following the reference time. The instant of the subsequent level change in the first direction is determined as a reference time relative to the next bit of data in the pulse signal. The data of a predetermined number of bits is continuously transmitted by repeatedly establishing reference times and judging the value of a bit based on the time period which extends from the reference time to a subsequent level change.
