Figure 29. PAL Vsync End
PVENDDELO PAL Vsync End Delay on Odd Field,
Address 0xE9[7]
When PVENDDELO is 0 (default), there is no delay.
Setting PVENDDELO to 1 delays Vsync going low on an odd
field by a line relative to PVEND.
PVENDDELE PAL Vsync End Delay on Even Field,
Address 0xE9[6]
When PVENDDELE is 0 (default), there is no delay.
Setting PVENDDELE to 1 delays Vsync going low on an even
field by a line relative to PVEND.
PVENDSIGN PAL Vsync End Sign, Address 0xE9[5]
Setting PVENDSIGN to 0 (default) delays the end of Vsync.
Set for user manual programming.
Setting PVENDSIGN to 1 advances the end of Vsync.
Not recommended for user programming.
PVEND[4:0] PAL Vsync End, Address 0xE9[4:0]
The default value of PVEND is 10100, indicating the PAL 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.
PFTOGDELO PAL Field Toggle Delay on Odd Field,
Address 0xEA[7]
When PFTOGDELO is 0 (default), there is no delay.
Setting PFTOGDELO to 1 delays the F toggle/transition on an
odd field by a line relative to PFTOG.
PFTOGDELE PAL Field Toggle Delay on Even Field,
Address 0xEA[6]
When PFTOGDELE is 0, there is no delay.
Setting PFTOGDELE to 1 (default) delays the F toggle/
transition on an even field by a line relative to PFTOG.
PFTOGSIGN PAL Field Toggle Sign, Address 0xEA[5]
Setting PFTOGSIGN to 0 delays the field transition. Set for user
manual programming.
Setting PFTOGSIGN to 1 (default) advances the field transition.
Not recommended for user programming.
PFTOG PAL Field Toggle, Address 0xEA[4:0]
The default value of PFTOG is 00011, indicating the PAL field
toggle position.
For all NTSC/PAL field timing controls, the F bit in the AV
code and the Field signal on the FIELD/DE pin are modified.
