Abstract: A computer-implemented method for data communication bus address sharing can include selecting, by at least one processor, one of two or more peripheral devices sharing an address of a data communication bus. The method can additionally include modulating, by the at least one processor, a duty cycle of a clock signal transmitted over the data communication bus to the two or more peripheral devices, wherein the modulating causes a low period of the clock signal to satisfy a threshold condition for indicating selection of the selected one of the two or more peripheral devices. The method can also include performing, by the at least one processor using the address, data communication over the data communication bus with the selected one of the two or more peripheral devices. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: A disclosed method for restoring bus functionality includes detecting, by an automatic bus recovery block, that at least one target device on a bus pulls at least one line of the bus to a low level. The method also includes initiating, by the automatic bus recovery block, a timer to time a duration of the low level of the line. Additionally, the method includes detecting, by the automatic bus recovery block, that the duration of the low level of the line exceeds a predetermined time limit. Furthermore, the method includes alerting, by the automatic bus recovery block, a controller device on the bus that the duration of the low level exceeds the predetermined time limit to reset the line of the bus to a high level. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: A method for operating a system including a voltage regulating power supply includes sensing a local voltage on a first node of the system and a remote voltage on a second node of the system. The first node and the second node are in a conductive path coupled to a load of the system. The first node is closer to a power stage of the voltage regulating power supply than the second node. The second node is closer to the load than the first node. The method includes detecting a load release event based on the local voltage, the remote voltage, and at least one predetermined threshold value.
