"WebBy default, the MOSI line is set to 1 to indicate that no message is being sent. The process of sending a message begins with placing its most-significant bit on the MOSI line and then toggling the SD CLK signal from 0 to 1 and then back from 1 to 0. Then, the second bit is placed on the MOSI line and again the SD CLK signal is toggled twice. " - Cache mosi
