    Abstract: Data bus activation in an electronic device is provided. In one aspect, a host circuit determines a cumulative potential representing a cumulative fractional bus activation vote on a data line(s) in the data bus. The host circuit activates the data bus when the cumulative potential is greater than a configurable bus activation threshold. In another aspect, a device circuit(s) determines a selected signal strength threshold that is less than determined signal strength of an incoming signal. Accordingly, the device circuit(s) asserts a fractional potential corresponding to the selected signal strength threshold on the data line(s) as a fractional bus activation vote in the cumulative fractional bus activation vote. By activating the data bus based on the cumulative fractional bus activation vote, the host circuit can support timely data bus activation while preventing the data bus from being falsely activated, thus improving robustness of data bus activation in the electronic device.

    Abstract: Systems and methods to transfer master duties to a slave on a communication bus are disclosed. A master of a communication bus determines that one or more slaves are capable of serving as a sub-master, including providing a clock signal and owning control information bits. Once that determination is made, the master may determine that processing within the master is not required for a particular activity on the bus. The master then alerts one such capable slave to prepare to assume sub-master duties. Once the slave confirms that the slave is ready to assume the sub-master duties, the master may transmit a handover frame on the bus, and the slave begins acting as a sub-master. The master may then enter a low-power state, which may promote power savings, reduce heat generation, and provide other advantages.

    Abstract: Operating M-PHY communications protocol over a Serial Advanced Technology Attachment SATA-based interface and related devices, systems, and methods are disclosed. In one embodiment, the system operates the M-PHY communications over a SATA interface. Related cables, connectors, systems, and methods are also disclosed. In particular, embodiments of the present disclosure take the M-PHY standard compliant signals and direct them through a SATA compliant connector (and optionally cable) so as to allow two M-PHY standard compliant devices having SATA connectors to communicate.
