error accumulated in the line immediately following the fall of VVALID is reset. Therefore, the pixel count
for the line that was reset will change. In addition, where the condition of VTR and other signals is poor in
the FIFO-2 mode, the FIFO reset line might break in before the fall of VVALID.
In the above table, “V blank” indicates the line count during the “L” period of the VVALID signal, “Active
line” the line count during the “H” period of the VVALID signal, and “Total line” the line count in 1 field.
