When IDF = 9 (YCrCb 8-bit mode), H and V sync signals can be embedded into the data stream. In this mode, the
embedded sync will follow the CCIR656 convention, and the first byte of the “video timing reference code” will be
assumed to occur when a Cb sample would occur if the video stream was continuous. This is delineated in Table 8
shown below.
.
In this mode the S[7.0} contains the following data:
S[6]
S[5]
S[4]
Bits S[7] and S[3-0] are ignored.
