Reuse of digital interface for multiple components

摘要

In one embodiment, a circuit can selectively adjust a current for driving a load. The circuit includes a sensor configured to measure a magnetic field associated with the current and provide a sensor voltage representative thereof. A control circuit is configured to selectively adjust the current as a function of the sensor voltage and a time-varying voltage threshold. Other methods and systems are also disclosed.

1. A circuit for communicating a digital baseband signal, comprising:
first receiver circuitry for providing first application data; second receiver circuitry for providing second application data; a frame buffer configured to selectively receive the first application data or the second application data as a function of a control signal, and to facilitate the presentation of the selectively received data to a digital baseband processor via a common digital interface; and third receiver circuitry configured to continuously provide third application data to the frame buffer in parallel with the selectively received data, where the frame buffer has at least one FIFO associated with the selectively received data and at least another FIFO associated with the third application data.
