Background
According to the prior art, data is transmitted in a serial manner by means of a device having a data line and a clock line. Such devices may be designed to use known two-wire transmission protocols, such as SPI or I2C or TWI. Such devices are also known as synchronous serial two-wire buses. In such a device, individual bits (bits) are transmitted in sequence on the line. To increase data transfer on such devices, asynchronous data transfer protocols may be used in which start and stop bits must be used to represent the individual data words themselves.
