摘要： A printhead assembly (902) includes an integrated circuit (300a,300b) to drive a plurality of fluid actuation devices. The integrated circuit (300a,300b) includes a status register (304), a plurality of interfaces including a mode interface (312), a fire interface (314), and a data interface (310) and control logic (302a,302b). The control logic (302a,302b) is to enable reading of the status register (304) in response to both a signal on the mode interface (312) transitioning to logic high with a logic high signal on the data interface (310) and transitioning a signal on the fire interface (314) to logic high with the signal on the data interface (310) floating.

摘要： An integrated circuit to access a memory associated with a fluid ejection device includes a plurality of memory cells, an address decoder, activation logic, and configuration logic. The address decoder selects memory cells in response to an address. The activation logic activates selected memory cells based on a data signal and a fire signal. The configuration logic enables or disables access to the plurality of memory cells.
