This value specifies the vertical 

sync alignment for the start of the interlaced second field expressed in terms of the 

absolute pixel number relative to the horizontal active display start.  

This value will only be used if the PIPEBCONF is programmed to an interlaced mode 

using vsync shift. Otherwise a legacy value of floor[htotal / 2] will be used. 

Typically, the interlaced second field vertical sync should start one pixel after the point 

halfway between successive horizontal syncs, so the value of this register should be 

programmed to:  

(horizontal sync start - floor[horizontal total / 2]) (use the actual horizontal sync start 

and horizontal total values and not the minus one values programmed into registers). 

This vertical sync shift only occurs during the interlaced second field. In all other cases 

the vertical sync start position is aligned with horizontal sync start.
