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 signal 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.
NVENDDELE, NTSC VSYNC End Delay on Even Field,
Address 0xE6[6]
When NVENDDELE is set to 0 (default), there is no delay.
Setting NVENDDELE to 1 delays VSYNC from going low on an
even field by a line relative to NVEND.
NVENDSIGN, NTSC VSYNC End Sign, Address 0xE6[5]
Setting NVENDSIGN to 0 (default) delays the end of VSYNC.
Set for user manual programming.
Setting NVENDSIGN to 1 advances the end of VSYNC (not
recommended for user programming).
