Filed: 1990-11-28
Abstract: PURPOSE:To improve the transfer speed of data by operating a receivable signal on a transmission side with data, and providing a function like a data line and enabling usage in combination with a normal data line. CONSTITUTION:When the receivable signal SRDY sent from a reception side 11 to the transmission side 10 falls from 'H' to 'L', a clock CLK and data are outputted from the transmission side 10. The transmission side 10 outputs the data every time the clock CLK falls from 'H' to 'L' and the reception side 11 receives the data every time the clock CLK rises from 'L' to 'H'. Once transfer is started, the transmission side 10 is enabled to operate the SRDY being received during the transfer. On the transmission, 8-bit data are delimited by every two bits, one of which is used as a data line artificially by operating the receivable signal SRDY with the data and transferred together with one bit of the normal data line. Consequently, the transfer speed can be increased.
