Abstract:
A method for serial transfer of data between two electronic bus stations, one being a master station and the other being a slave station, over a 3 line bus connection where a 1st line is dedicated to a clock signal, and a second line and a third line are dedicated to data signals or control signals, comprising the steps of:i) starting a data transfer from the master station to the slave station by sending a 1st edge signal from the master station to the slave station on said 2nd line; ii) in response to the 1st edge signal, the slave station switching the third line from an idle-state to an active state, after a 1st amount of time has elapsed from the occurrence of said 1st edge signal; and iii) commencing synchronous data transmission via said second and first lines after a 2nd amount of time has elapsed from the occurrence of the active state on the third line during which the third line stays in its active state, wherein the master station provides the clock signal to the slave station via the 1st line and the master station provides the data signals to the slave station via the second line.
