Data is sent byte-wise LSB first. The state of the data and strobe signals at the beginning of

transmission are fixed i.e. the state of data is logic high and the state of strobe is logic low.

The number of clock cycles between synchronization codes has to be even, both between

SOL (or SOF) – EOL (or EOF) and EOL (or EOF) – SOL (or SOF). This ensures

synchronization is possible with minimum complexity to achieve the fastest possible

implementation. The strobe signal can be gated when using the data/strobe signaling, but

only if the number of clock cycles is even between synchronization codes.

If the number of transmission clock cycles between synchronization codes is even, it

ensures that for each synchronization code sequence FF0000h there will be corresponding

strobe sequence of 55AAAAh as illustrated in the Figure 3 below.
