2.3.18.6 Window-Start (x, y) Registers (Index 10, 11, 14, 15 hex)
These registers are used to specify the (x,y) coordinate of the upper-left corner of the crosshair-cursor
window or auxiliary window. The window start is not updated until the vertical retrace interval after the Y MSB
register has been written to by the MPU. Bits D4–D7 of the window-start X and Y MSB registers are always
logic zero.

Index = 15 (hex)

The window-start X and Y values to be written are calculated as follows:
Wx = desired display screen x position
Wy = desired display screen y position
Values from 0000 (hex) to 0fff (hex) can be written into the window-start X and Y registers. The values written
into the window-start X and Y registers should be relative to the first displayed pixel on the screen; i.e., (0,0).
The window-start location specified is the first location inside the window. For the crosshair cursor or
auxiliary window to be displayed, the window-start registers must specify a point on the active display.
2.3.18.7 Window-Stop (x, y) Registers (Index 12, 13, 16, 17 hex)
These registers are used to specify the (x,y) coordinate of the lower-right corner of the crosshair-cursor or
auxiliary window. The window stop is not updated until the vertical retrace interval after the Y MSB register
has been written to by the MPU. Bits D4–D7 of the window-stop X and Y registers are always logic zero.

The window-stop location specified is the last location inside the window. For the crosshair-cursor or
