Abstract
The present invention provides a data transmission method for sending parallel data from a transmitting side to a receiving side. After transmitting an i-th item of data (DT.sub.i), the transmitting side sends a high-level data transmission signal (DS) to the receiving side at the expiration of a predetermined period of time (t.sub.1). In response to receipt of the high-level data transmission signal (DS), the receiving side reads the i-th item of data (DT.sub.i) and sends a high-level data reception signal (DR) to the transmitting side. The transmitting side ends the transmission cycle for the i-th item of data upon receiving the high-level data reception signal (DR). After transmitting the next or (i+1)th item of data (DT.sub.i+1), the transmitting side sends a low-level data transmission signal (DS) at the expiration of the predetermined period of time (t.sub.1). In response to receipt of the low-level data transmission signal (DS), the receiving side reads the (i+1)th item of data (DT.sub.i+1) and sends a low-level data reception signal (DR) to the transmitting side. The transmitting side ends the transmission cycle for the (i+1)th item of data upon receiving the low-level data…
