Abstract
A method and system for issuing pen-input commands from a computer system to a controller for a touchpad to initialize the controller to the desired operating mode for the touchpad. The touchpad may emulate the function of a mouse pointing device or provide absolute coordinates of a pointed object such as human finger, a stylus, or a pen upon the touchpad. The pen-input commands will set the autocursor mode and boundaries for the edgezone and the deadzone upon the touchpad, the times for the presence detect signal to create the stroke signal, the threshold of movement of the pointed object upon the touchpad necessary to send the mouse protocols to the computer system, the mode of the pen-input mouse controller is to operate, whether the pen-input mouse controller is to send the mouse protocol or the pen-input computer interface protocol to the computer system, the averaging algorithm to used by the absolute coordinate calculator, the minimum pressure required to activate the touchpad, the parameters for the autocursor mode operation, and the time parameters for the autopower save circuit.
