FLUID EJECTION DEVICE WITH FIRE PULSE GROUPS INCLUDING WARMING DATA

A fluid ejection device includes a number of primitives, each receiving a same set of addresses and including a number of ejection chambers, each corresponding to a different address of the set of addresses and including a drive bubble formation mechanism and a drive bubble detect (DBD) mechanism. Input logic receives nozzle column data groups (NCG), each NCG including fire pulse groups (FPG), each FPG including DBD data having an enable value or disable value, and ejection data bits, each ejection data bit corresponding to a different one of the primitives. For each FPG of each NCG, activation logic identifies the FPG as a DBD FPG when the DBD data has the enable value and activates in each primitive the drive bubble formation mechanism and the DBD mechanism identified by the DBD FPG to perform a DBD measurement.
