CP_END_VBI_EVEN[11:0], CP Map, Address 0xA9 [3:0] and 0xAA, [7:0]
CP_END_VBI_EVEN[11:0] specifies the line number where the VBI region ends. This is used for
even fields when the decoder is processing an interlaced input and not used when the decoder is
processing a progressive input.
Function
CP_END_VBI_EVEN
[11:0]
0x0

It is also possible to adjust the position of the HSync and VSync signals. The following controls to
adjust these are signed numbers to allow adjustment in either direction from the current position:
•
START_HS[9:0],
•
END_HS[9:0],
•
START_VS[3:0],
•
END_VS[3:0],

Description
Default value.
Sets start of window during which the clamp is ignored. This register
stores unsigned number of pixel clocks between start position of the
window relative to leading edge of the VSync. This control should
only be used when VID_STD[5:0] is set for auto graphics mode.
