Abstract: A touch-sensitive depressible button with multiple depression thresholds is provided. When the button is depressed to a first depression threshold, the touch sensor can be switched from a low-power, non-sensing state to a sensing state. When the button is depressed to a second depression threshold, the touch sensor can sense the touch context and input can be generated based on the depression and the touch context. In this way, the touch-sensitive depressible button with multiple depression thresholds can facilitate timely switching of the touch sensor to a sensing state.

Abstract: A touch sensing system is disclosed that can include a firmware module stored in memory and executed at run time to store values into a hardware register for configuring various parameters of capacitive sensing system to reduce quantization and scan noise, reduce interference with neighboring electronics, and avoid noise aggressors. In addition, a serial peripheral interface (SPI) can be employed to allow a host controller to access information about the performance of touch controller and send communications back to touch controller to make run-time changes to the parameters of touch controller.
