DESCRIPTION
BXO defines a horizontal offset,
counted in LLC cycles, after
selected horizontal sync edge till
data is read from the FIFO
in field memory mode the
following offsets depending on the
horizontal scaling ratio must be
selected to guarantee the correct
outrun behaviour of the scaler
(see Table 70). The video window
is select by ‘NumLines’,
‘NumBytes’, ‘pitch’ and ‘base
address’
horizontal upscaling:

for luminance and 80H for
chrominance values) for not
qualified bytes.
