NVENDDELE NTSC VSync End Delay on Even Field,
Address 0xE6 [6]
Rev. 0 | Page 42 of 96
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/
