Embedded Sync Only In 8b mode.. there is only one channel on
data[7:0]. In 16b mode.. there are two channels. The Luma Channel
is on data[15:8]. The Chroma Channel is on data[7:0]. In 24b mode..
there are three channels. The R channel is on data[23:16].. the G
channel is on [15:8].. and the B channel is on data[7:0].
00 = Use data[7:0] to extract control codes.
01 = Use data[15:8] to extract control codes.
10 = Use data[23:16] to extract control codes.
11 = Undefined
In 16b and 24b modes.. this register is also used to select the
channel from which Ancillary Data is extracted. The Ancillary Data
channel must be the same as the control code channel. For 8b
mode.. the anc_chan_sel_8b register is used to select the Luma or
Chroma channel from which Ancillary Data is taken.
