When this bit is set, the chroma components are
converted to 2’s-complement values with the centers at 0
instead of 128. This is done by effectively inverting the
MSB of the Cr and Cb values.
When this bit is set, the Vertical Sync pulse is an
Even/Not Odd field input. When this bit is cleared, the
Vertical Sync input is a pulse.
Clear this bit when writing to this register.
