In SwivelView 180°, these registers set the horizontal coordinates (x) of the sub-window’s
top left corner. Increasing values of x move the top left corner towards the right in steps of
32
÷
bits-per-pixel (see Table 8-3: )
Program the Sub-Window X End Position registers so that
sub-window X end position registers = (panel width - x)
÷
(32
÷
bits-per-pixel) - 1
Note
panel width - x must be a multiple of 32
÷
bits-per-pixel.
In SwivelView 270°, these registers set the vertical coordinates (y) of the sub-window’s
top right corner. Increasing values of y move the top right corner downwards in steps of 1
line.
Program the Sub-Window X End Position registers so that
sub-window X end position registers = panel width - y - 1
