Figure 22. NTSC VSync Begin
NVBEGDELO NTSC VSync Begin Delay on Odd Field,
Address 0xE5 [7]
When NVBEGDELO is 0 (default), there is no delay.
Setting NVBEGDELO to 1 delays VSync going high on an odd
field by a line relative to NVBEG.
NVBEGDELE NTSC Vsync Begin Delay on Even Field,
Address 0xE5 [6]
When NVBEGDELE is 0 (default), there is no delay.
Setting NVBEGDELE to 1 delays VSync going high on an even
field by a line relative to NVBEG.
NVBEGSIGN NTSC VSync Begin Sign, Address 0xE5 [5]
Setting NVBEGSIGN to 0 delays the start of VSync. Set for user
manual programming.
Setting NVBEGSIGN to 1 (default) advances the start of VSync.
Not recommended for user programming.
NVBEG[4:0] NTSC VSync Begin, Address 0xE5 [4:0]
The default value of NVBEG is 00101, indicating the NTSC
VSync begin position.
For all NTSC/PAL VSync timing controls, both the V bit in the
AV code and the VSync on the VS pin are modified.

NVENDDELO NTSC VSync End Delay on Odd Field,
Address 0xE6 [7]
When NVENDDELO is 0 (default), there is no delay.
Setting NVENDDELO to 1 delays VSync from going low on an
odd field by a line relative to NVEND.
