normal operation of the vertical scaler; default after reset
vertical upscaling is enabled
controls the vertical interpolation filter, see Table 35; the filter is not available if
YUPSC = 1
normal operation of the cursor generator; default after reset
the cursor will be zoomed by a factor of 2 in both directions
expected input level swing is 16 to 235 (8-bit RGB); default after reset
expected input level swing is 0 to 255 (8-bit RGB)
no horizontal interpolation filter; default after reset
interpolation filter for horizontal upscaling is active
