Abstract
A data transmission device for serial, synchronous transmission of data includes a master device and a slave device which can be linked by at least one data transmission line and a clock signal line. The master and slave devices can be linked by an additional ready signal line for transmitting a ready signal from the slave device to the master device. When the slave device has completed a data reading operation, a ready signal can be generated for the master device. The master device is able to initiate a further writing operation to the slave device only after receiving the ready signal from the slave device. Suppression of interference by the slave device may be enhanced.
