NVEND[4:0], NTSC 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 signal 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.
NFTOGSIGN, NTSC Field Toggle Sign, Address 0xE7[5]
Setting NFTOGSIGN to 0 delays the field transition. Set for
user manual programming.
Setting NFTOGSIGN to 1 (default) advances the field transition
(not recommended for user programming).
NFTOG[4:0], NTSC Field Toggle, Address 0xE7[4:0]
The default value of NFTOG is 00011, indicating the NTSC
field toggle position.
For all NTSC/PAL field timing controls, both the F bit in the
AV code and the field signal on the FIELD pin are modified.
