Abstract: A functional timing sensor includes a setup time violation detecting circuit, a hold time violation detecting circuit, and an interface from the setup time violation detecting circuit and the hold time violation detecting circuit. The interface provides a notification upon detection of a violation by either the setup time violation detecting circuit or the hold time violation detecting circuit.

Abstract: A method and apparatus for receiving digital audio data which does not require the recovery of a clock from the data. Instead, the digital audio data is sampled at a rate greater than a clock rate of the digital audio data. Appropriate transitions in the digital audio data are detected to allow reconstruction of digital values represented by the digital audio data.

Abstract: A method for determining a position of a joystick in data communication with a processor and having an initial state that includes steps of varying the initial state in response to a signal from the processor; returning the joystick to the initial state after a duration of time, with the duration of time being dependent upon the position amongst a plurality of positions. A plurality of poll operations of the joystick are executed to sense the returning step. Each of the polling operations results in a data signal being transferred from the joystick indicating the state of the same, with consecutive poll operations being separated by a predetermined segment of time, defining a first interval and consecutive data signals operations being separated by a time period, defining a second interval. The second interval is increased to be greater than the first interval, the duration of time is measured by determining a number of data signals received by the processor between the varying step and the returning step.
