Cursor Control
C:
When C = 1, the window cursor display is started. The display mode is selected by the CM1D0 bits, and
the display area is specified in a dot unit by the horizontal cursor position register (HS6D0 and HE6D0 bits)
and vertical cursor position register (VS6D0 and VE6D0 bits). For details, see the Window Cursor Display
section.
CM1D0:
The display mode of the window cursor is selected. These bits can display a white-blink cursor,
black-blink cursor, black-and-white reversed cursor, and black-and-white-reversed blink cursor.

Double-height Display Position
DS6D0:
Specify any common raster-row position where the double-height display starts. Note that no
scrolling is done by vertical scrolling. For details, see the Double-height Display section.
DE6-0:
Specify any common raster-row position where the double-height display ends. Set the end
position of the double-height display after the start position of the double-height display, satisfying the
relationship DS6D0
DE6D0. When the area specifying the double height has an odd number of raster-
rows, the double-height display is done for the DE6D0 + 1 raster-rows.
When the double-height display is not used, set the DHE bit in the display-control instruction register to 0.
