CHRONTEL
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 be similar to 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 6 shown below.
In this mode, the S[7:0] byte contains the following data:
S[6]
S[5]
S[4]
Bits S[7] and S[3-0] are ignored.
