(see commands 05 and 0A), that range does not apply.
05 Set mayiwiiM x and Y values the mouse can attain.
Sequence of parameters transmitted to the interface:
XMAX, low byte
XMAX, high byte
YMAX, low byte
YMAX, high byte
The relation between the X/Y co-ordinates computed by th«
Mouse In terface and the actual distance covered by the
mouse varies according to the type o f mouse being used,
The default settings (XMAX = 640, YMAX = 400) correspond
to practicable ranges for using a mouse on a desk top.
