NVBEGDELO NTSC Vsync Begin Delay on Odd Field,
Address 0xE5[7]
When NVBEGDELO is 0 (default), there is no delay.
Setting NVBEGDELO to 1, delay 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 on the VS pin are modified.
