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]
0 (default)—No delay.
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]
0—No delay.
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]
0—Delays the field transition. Set for manual programming.
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/DE pin are
modified.
PVBEGDELO, PAL Vsync Begin Delay on Odd Field,
Address 0xE8 [7]
0 (default)—No delay.
1—Delays vsync going high on an odd field by a line relative to
PVBEG.
PVBEGDELE, PAL Vsync Begin Delay on Even Field,
Address 0xE8 [6]
0 (default)—No delay.
1 (default)—Delays vsync going high on an even field by a line
relative to PVBEG.
PVBEGSIGN, PAL Vsync Begin Sign, Address 0xE8 [5]
0—Delays the beginning of vsync. Set for user manual
programming.
1 (default)—Advances the beginning of vsync. Not
recommended for user programming.
PVBEG [4:0], PAL Vsync Begin, Address 0xE8 [4:0]
The default value of PVBEG is 00101, indicating the PAL 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.
