Horizontal Cursor Position (R12h)
Vertical Cursor Position (R13h)
HS6–0: Specify the start position for horizontally displaying the window cursor in a pixel unit. The cursor is
displayed from the 'set value + 1' pixel. Ensure that HS6-0 ≤ HE6-0.
HE6–0: Specify the end position for horizontally displaying the window cursor in a pixel unit. The cursor is
displayed to the 'set value + 1' pixel. Ensure that HS6-0 ≤ HE6-0.
VS6–0: Specify the start position for vertically displaying the window cursor in a raster-row unit. The cursor
is displayed from the 'set value + 1' raster-row. Ensure that VS6-0 ≤ VE6-0.
VE6–0: Specify the end position for vertically displaying the window cursor in a raster-row unit. The cursor
is displayed to the 'set value + 1' raster-row. Ensure that VS6-0 ≤ VE6-0.
