Figure 44. 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 signal 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 pin are modified.
