Function
cp_end_vbi_even[11:0]
0x000 <<
The following controls are intended only for use with HDMI 3D standards.
cp_start_vbi_r[11:0], Addr 44 (CP), Address 0x2A[7:0]; Address 0x2B[7:4]
This control is used to manually set the value for the start position of the VBI region. This is the extra blank region preceding the odd
right (R) field in the 3D TV field alternative packing format supported by HDMI. It is not required to set this value. In normal
operation, this parameter is automatically calculated from the input.
cp_end_vbi_r[11:0], Addr 44 (CP), Address 0x2B[3:0]; Address 0x2C[7:0]
This control is used to manually set the value for the end of VBI position. This is the extra blank region preceding the odd right field in
the 3D TV field alternative packing format supported by HDMI. It is not required to set this value. In normal operation, this parameter
is automatically calculated from the input.
cp_start_vbi_even_r[11:0], Addr 44 (CP), Address 0x2D[7:0]; Address 0x2E[7:4]
This control is used to manually set the value for the start position of the VBI region. This is the extra blank region preceding the even
right field in the 3D TV field alternative packing format supported by HDMI. It is not required to set this value. In normal operation,
this parameter is automatically calculated from the input.
cp_end_vbi_even[11:0], Addr 44 (CP), Address 0xA9[3:0]; Address 0xAA[7:0]
This control is used to set the manual value for the end of the VBI region position for even fields. It is an unsigned value. It sets the total
number of lines at the end of the even frame of interlaced standard. Programming is optional and should only be performed when the
part is set in autographics mode.

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:
• cp_start_hs[12:0]
•
cp_end_hs[12:0]
• cp_start_vs[5:0]
• cp_end_vs[5:0]
•
cp_start_vs_even[10:0]
• cp_end_vs_even[10:0]
cp_start_hs[12:0], Addr 44 (CP), Address 0x22[4:0]; Address 0x23[7:0]
This control is used to set the position of the start of the HSync output signal in the CP core in autographic mode only. Programming of
this control is optional and should only be performed when the part is set in autographics mode. The value is unsigned.
