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.

NVEND NTSC[4:0] Vsync End, Address 0xE6[4:0]
The default value of NVEND is 00100, indicating the NTSC
Vsync end 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.
NFTOGDELO NTSC Field Toggle Delay on Odd Field,
Address 0xE7[7]
When NFTOGDELO is 0 (default), there is no delay.
Setting NFTOGDELO to 1 delays the field toggle/transition on
an odd field by a line relative to NFTOG.
NFTOGDELE NTSC Field Toggle Delay on Even Field,
Address 0xE7[6]
When NFTOGDELE is 0, there is no delay.
Setting NFTOGDELE to 1 (default) delays the field toggle/
transition on an even field by a line relative to NFTOG.
