Description
The plane X-direction memory width is set
between 16 and 4096 pixels, in 16 pixel units.
The start address in memory area is set for
plane n.
The Y direction start position of the plane n
wrap-around area is set in raster line units,
with the address set by DSA as reference.
The wrap-around Y-direction memory width is
set arbitrarily in the range 240 to 4095 lines.
The distance in the X direction to the display
start position is set in pixel units, taking the
address set by DSA as the origin.
The distance in the Y direction to the display
start position is set in raster line units, taking
the address set by DSA as the origin.
The X-direction display size of plane n is set in
pixel units.
The Y-direction display size of plane n is set in
raster line units.
The X-direction distance to the display position
is set in pixel units, taking the upper-left corner
of monitor as the origin.
The Y-direction distance to the display position
is set in raster line units, taking the upper-left
corner of monitor as the origin.
The Y-direction memory area of plane n is set
in raster line units.
