0h
Embedded Sync Only
0 = Ignore the protection bits in the XV (fvh) codeword header. This
setting is typically desired.
1 = Use the protection bits in an attempt to do error correction for the
fvh control bits.

Embedded Sync Only
0 = For 2x/4x mux mode.. srcnum is in the least significant nibble of
the XV/fvh codeword (srcnum replaces the protection bits)
1 = For 2x/4x mux mode.. srcnum is in the least significant nibble of
a horizontal blanking pixel value
