<p>PROBLEM TO BE SOLVED: To surely receive data from a data transmitter side in response to a revision of a data transmission rate, even when the data transmission rate is revised on the way to data transmission or reception. SOLUTION: Since the bit period of start bits is detected, based on a bit time width measurement of a start bit '0' with a trailing detection pulse 13 and a leading detection pulse 12 from a start bit detection circuit 21 to a counter 22 at a data receiver side receiving start bits '0', '1' from a data transmitter side, data from the start bit '1' to a stop bit '1' are surely received sequentially in bit units.</p> |
