    摘要: Capacitive detection systems, modules, and methods. In one embodiment, time interval measurement(s) are generated that are monotonic functions of the capacitance(s) of capacitive sensor(s) in a capacitive sensing area. In one embodiment, the generated time interval measurement(s), or any other monotonic function(s) of capacitance(s) of capacitive sensor(s) in a capacitive sensing area, may be analyzed to detect the presence of an object near the capacitive sensing area and/or to detect the position of an object near the capacitive sensing area.

    摘要: An improved system is described for allowing an embedded controller and a host processor to share access to modules in a computer system. The shared access system of the present invention enables exclusive, one-at-a-time access by a processor to a module and concurrent access by more than one processor to a module. An internal bus with two power sources is used to allow continued access by one of the processors when one of the two power sources is not providing power. Asynchronous clocking is provided to allow increased throughput to modules. An example of a protocol that allows an embedded controller to access more than one module is also described.

    摘要: A controller handles host commands from a host processor and also interfaces the host processor to a serial device. Storage circuitry (e.g., a shift register) of the controller holds a predetermined plurality of data bits. State machine circuitry controls the storage circuitry for serial bit-level communication (e.g., using a PS/2 protocol) between the storage circuitry and the serial device. A processor executes code from a program memory. In particular, the program code causes the processor to detect that a host command has been received by the controller from the host processor and causes an action corresponding to the host command received. Because the processor is not involved with the serial bit-level communication between the storage circuitry and the serial device, the processor executing the software can handle host commands without affecting the serial bit-level communication.
