Abstract: Systems, methods, and apparatus are configured to enable a receiver to provide feedback. A feedback mechanism enables a transmitting device to identify the provider of feedback for a multicast transmission, and the feedback transmitted by one or more individual receivers of the multicast transmission. A method includes receiving a multicast write command from the serial bus in a first datagram, writing a data byte received in a first data frame of the first datagram to a register address identified by the first datagram, and providing device-specific feedback regarding the first datagram in a multibit slot within the second data frame. The multibit slot is one of a plurality of sequential multibit slots defined for the second data frame. Each multibit slot in the plurality of sequential multibit slots may provide device-specific feedback from one receiving device addressed by the multicast write command.

Abstract: Systems, methods, apparatus and techniques are described that provide point-to-point capabilities without the expected increase in input/output pad usage. In some examples, point-to-point data lines are provided between a host and multiple slave devices and timing of communication is controlled using a clock signal shared by the multiple slave devices. An apparatus has a plurality of bus master circuits configured to control point-to-point communication with corresponding slave devices and a clock generation circuit configured to provide pulses in a serial bus clock signal when one or more bus master circuits are in an active state, and further to idle the serial bus clock signal when all bus master circuits are idle. Each bus master circuit may be configured to communicate with its corresponding slave device in accordance with the timing provided by the serial bus clock signal that is transmitted over a common clock line to each slave device.

Abstract: Systems, methods, and apparatus for communication over a serial bus in accordance with an I3C protocol are described that enable a non-participating device to cause a master device on an I3C bus transmit a STOP condition that terminates a transaction with a slave device coupled to the I3C bus. A method performed at a master device coupled to a serial bus includes initiating a transaction between the master device and a first slave device, terminating the transaction before completion of the transaction when a second slave device intervenes in the transaction, and servicing the second slave device after terminating the transaction. The transaction may include transmissions of data frames over the serial bus. The second slave device may intervene when it is not a party to the transaction.

Abstract: Systems, methods, and apparatus are described. A method for data communication performed at a master device includes configuring a serial interface for a point-to-point mode of operation, transmitting a first two-bit command through the serial interface, the two-bit command including a one-bit address and a read/write bit, and initiating a transaction through the serial interface. The transaction may be identified by the two-bit command and is conducted in accordance with an I3C protocol. The transaction may include the transfer of one or more data frames formatted in accordance with the I3C protocol. The method may include receiving an acknowledgement from a slave device in response to the first two-bit command.

Abstract: Systems, methods, and apparatus for communication over a serial bus in accordance with an I3C protocol are described. A master device coupled to the serial bus may detect signaling on the serial bus corresponding to an in-band interrupt asserted by a slave device that is addressable by a first device identifier, receive a second device identifier transmitted by the slave device in relation to the in-band interrupt, use the second device identifier to select an execution environment, and interrupt the execution environment responsive to the in-band interrupt. The slave device may use the first device identifier in transactions conducted over the serial bus. After detecting an event generated by an event source, the slave device may initiate an in-band interrupt on the serial bus, and may transmit the second device identifier to indicate the event source during an in-band interrupt handling procedure.

Abstract: In an embodiment, a control device that is configured to onboard a target device to a secure local network by discovering a set of devices over a bootstrapping interface, establishing a bootstrap connection to at least one device from the set of devices in response to the discovery without authorizing the at least one device to access the secure local network, instructing the at least one device via the bootstrap connection to activate an observable function that is configured to be observable to one or more observation entities that are separate from the control device and are in proximity to the at least one device, determining whether an operator of the control device verifies that the observable function has been successfully detected as performed by the target device and selectively authorizing the at least one device to access the secure local network based on the determination.

Abstract: In some aspects, the present disclosure provides a method for communicating audio data. In one example, the method includes determining whether a condition for each transport opportunity on an audio channel is met based on an audio sample rate and a channel rate of the audio channel. For each transport opportunity, upon determining that the condition is met for the transport opportunity, the method also includes transmitting audio sample data over the transport opportunity or receiving audio sample data at the transport opportunity.

Abstract: Systems and methods for multi-threshold sensing at an audio receiver, and systems and methods for calibrating an audio system to optimize for the specific configuration of the audio system are disclosed herein. In some implementations of a multi-threshold receiver, at least one additional voltage level is selected to trigger latching events within the receiver based on changes of the receiver input (which includes differential signals Vp and Vn) and in turn, to generate internal signals within the multi-threshold receiver, and then logic operations are performed on these internal signals to generate the output of the multi-threshold receiver.

Abstract: System, methods and apparatus are described that can improve available bandwidth on a SoundWire bus without increasing the number of pins used by the SoundWire bus. A method performed at a master device coupled to a SoundWire bus includes providing a clock signal by a first master device over a clock line of a SoundWire bus to a first slave device and a second slave device coupled to the SoundWire bus, transmitting first control information from the first master device to the first slave device over a first data line of the SoundWire bus, and transmitting second control information from the first master device to the second slave device over a second data line of the SoundWire bus. The first control information may be different from the second control information and is transmitted concurrently with the second control information.
