A fluid-ejection device includes physical data lines, a controller, and a fluid-ejection mechanism. The physical data lines communicatively connect the controller and the fluid-ejection mechanism. The controller is to assert a logical and virtual nozzle-fire-restart line to denote that a first data sub-packet of a new data packet of nozzle data for a predetermined sequence of fluid-ejection nozzles of the fluid-ejection mechanism is being transmitted over the physical data lines. The fluid-ejection mechanism is to listen for the controller to assert the logical and virtual nozzle-fire-restart line, to discern that the first data sub-packet of the new data packet is being transmitted over the physical data lines.

In an implementation, a selectable integrated circuit interface includes selectable integrated circuit interface configurations that can each interface an integrated circuit. A selection circuit generates a selection signal to select an individual selectable integrated circuit interface configuration, and logic couples a clock signal and data to a selected integrated circuit interface configuration.

Selectable integrated circuit interface

Systems, methods, and devices are provided for instruction architecture. One embodiment includes a first integrated circuit (IC). The first IC includes at least two instruction stacks and an arbiter coupled to the at least two instruction stacks. A second IC is provided. The first and the second ICs are coupled using a serial interface.
