1. A computing device comprising:

  • a touch sensor panel including a plurality of touch sensors;

    a processor configured to process data sensed from the touch sensor panel generated by a plurality of different types of scans of the touch sensor panel, the data including touch sense data indicative of an occurrence or absence of a touch event at the touch sensor panel;

    first logic circuitry configured to perform the plurality of different types of scans of the touch sensor panel in a sequence set by the processor, without further intervention from the processor, the plurality of different types of scans including at least a multi-stimulation touch scan to generate the touch sense data;

    second logic circuitry configured to stimulate the touch sensor panel; and

    sense channels configured to sense the touch sensor panel.
