Abstract: In an example there is provided a configurable integrated circuit. The configurable integrated circuit comprises a configuration pin, configuration circuitry, and a controller. The configuration pin is for coupling with an external memory device. The configuration circuitry is to determine a resistance value between the configuration pin and a reference voltage. The controller configured to select a configuration mode for the integrated circuit based on the resistance value determined by the configuration circuitry. The configuration mode is one of an internal configuration mode in which the integrated circuit is configured based on data stored in the integrated circuit, and an external configuration mode in which the integrated circuit is configured based on data read from an external memory device coupled to the configuration pin.

Abstract: A system for transmission of primary and secondary data, the system comprising: a bus; a parent node coupled to the bus; and a plurality of child nodes, each coupled to the bus, wherein: the parent node is configured to periodically transmit a time domain multiplexing (TDM) cycle beacon to the bus, wherein the TDM cycle beacon signals a start of a primary data transmission interval, and wherein the primary data transmission interval is a period reserved for transmission of primary data by the parent node and the plurality of child nodes; the parent node and each of the plurality of child nodes are operable to, responsive to the TDM cycle beacon, transmit primary data for a current TDM beacon period associated with the TDM cycle beacon to the bus during the primary data transmission interval; and the parent node and the plurality of child nodes are operable to transmit secondary data to the bus during a secondary data transmission interval between an end of the primary transmission interval and transmission by
