1. A method comprising: operating a digitizer system in a first mode of operation for detecting multi-touch fingertip and/or stylus, the first mode of operation associated with one or more processing routines performed by the digitizer system for processing data sampled from a digitizer sensor of the digitizer system, wherein the digitizer system is operated with an electronic device including software applications; receiving instructions to suspend or activate one of the processing routines to detect multi-touch fingertip and/or stylus, wherein the instructions are defined by a software application, the software application configured to receive input from the digitizer system; and updating operation of the digitizer system based on the instructions defined by the software application, wherein the updating includes suspending sampling the digitizer sensor for stylus detection or suspending scanning the digitizer sensor for fingertip detection and wherein the software application is configured to define the instructions based on accumulated data derived over an extended duration of time, the accumulated data characterizing how a user(s) typically operates the electronic device.
