Figure 29. NTSC Vsync Begin
NVBEGDELO, NTSC Vsync Begin Delay on Odd Field,
Address 0xE5 [7]
0 (default)—No delay.
1—Delays vsync going high on an odd field by a line relative
to NVBEG.
NVBEGDELE, NTSC Vsync Begin Delay on Even Field,
Address 0xE5 [6]
0 (default)—No delay.
1—Delays vsync going high on an even field by a line relative
to NVBEG.
NVBEGSIGN, NTSC Vsync Begin Sign, Address 0xE5 [5]
0—Delays the start of vsync. Set for user manual programming.
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.
