VS away from start of active video.
END_VS[3:0] , Addr 44 (CP), Address 0x7F[3:0]
A control to shift the position of the trailing edge of the VSync output by the CP core.
This register stores a signed value in a twos complement format. SEND_VS[3:0] is the number of lines by which the trailing edge of the
VSync is shifted (for example, 0x0F corresponds to a shift of one line toward the active video, 0x01 corresponds to a shift of 1 line away
from the active video).
Function
END_VS[3:0] Description
0x0 (default) Default value.
0x0 to 0x7 The trailing edge of the VSync is shifted toward the active video.
0x8 to 0xF The trailing edge of the VSync is shifted away from the active video.

2 VS away from start of active video.
START_VS_EVEN[3:0] , Addr 44 (CP), Address 0x89[7:4]
A control to shift the position of the leading edge of the Vsync output by the CP core.
This register stores a signed value in a twos complement format. START_VS_EVEN[3:0] is the number of lines by which the leading edge
of the Vsync is shifted (for example, 0x0F corresponds to a shift by one line toward the active video, 0x01 corresponds to a shift of 1 line
away from the active video).
Function
START_VS_EVEN[3:0]
0x0 to 0x7
0x8 to 0xF
Description
Default value.
The leading edge of the VSync is shifted toward the active video.
The leading edge of the VSync is shifted away from the active video.
Result
No move (default)
1 HS shift later than default
3 HS shift later than default
7 HS shift later than default
1 HS shift earlier than default
3 HS shift earlier than default
8 HS shift earlier than default
Result
No move (default)
1 HS shift later than default
3 HS shift later than default
7 HS shift later than default
1 HS shift earlier than default
3 HS shift earlier than default
8 HS shift earlier than default
Description
The leading edge of the even Vsync is shifted toward the active video.
The leading edge of the even Vsync is shifted away from the active video.
