A bus system, including a clock line, a first data line, and a second data line. The bus system further includes an initiator connected to a first end of the clock line, the first data line, and the second data line. The initiator sends a start indication on the clock line and the first data line, sends command bits followed by address bits on the first data line, and sends a stop indication on the clock line and the first data line. The bus system also includes a target connected to a second end of the clock line, the first data line, and the second data line. The target sends target acknowledge information followed by target interrupt information on the second line while the command bits and address bits are sent.

Enhanced serial peripheral interface

A protocol can specifie a power-sourcing voltage range that indicates power sourcing capabilities. Additional power sourcing capabilities can be communicated using voltage variations within the power-sourcing voltage range. A power-sourcing device can provide power to an external power-sinking device over a wired connection containing a plurality of wires. A voltage control circuit can be configured to drive a voltage over a wire of the plurality of wires. Processing circuitry can communicate, using the voltage control circuit, first power-sourcing capabilities to the external power-sinking device by setting the voltage over the wire to a value within the power-sourcing voltage range. The processing circuitry can also communicate, using the voltage control circuit, the additional power sourcing capabilities of the power-sourcing device using voltage variations on the wire, the voltage variations maintaining voltage on the wire within the power-sourcing voltage range.

Communications for power delivery solutions

A state-detection circuit facilitates the detection of the state of an input pin relative to several different types of input circuits. According to an example embodiment, a state-detection circuit includes a plurality of comparators and circuit components, configured to provide a plurality of binary output signals that collectively indicate a state of an input pin to which the comparators are coupled. The state-detection circuit is configured to facilitate the detection of several different types of input circuits, based upon the binary output signals.

Input pin state detection circuit and method therefor

Aspects of the instant disclosure are directed toward apparatuses that generate a power-related adjustment signal in response to the power signal. Digital-input-signal pads are included to communicate digital signals with a circuit external to the apparatus. Further, digital-input processing circuitry receives the digital signals from the digital-input-signal pad, and processes the received digital signals. Additionally, configuration circuitry applies the power-related adjustment signal to signals received at the digital-input-signal pad and, in response, detects the digital signals received.

Multi-level chip input circuit

According to an example embodiment of the present invention, a method is implemented for transmitting data between a Media Access Control Layer (MAC) () and a Physical Layer (PHY) () using an internal data bus for transmitting a set of internal symbols between the MAC () and PHY (). A subset of internal symbols does not have a corresponding PHY symbol. An external data bus carries data symbols. An external interface () provides command information on one or more dedicated command lines and provides the data symbols. An encoder () encodes the provided command information into one or more of the subset of internal symbols. An internal interface () transmits the one or more of the subset of internal symbols and the data symbols between the MAC () and PHY () using the internal data bus.
