8.5 Flag and Flag Mask Registers
a maximum of 8 flags plus the masks and destination IDs associated with those flags. The typical flag register content is
shown below table. The flags within a register are selected to generate same interrupt or generate doorbells destined for
the same location. The interrupting flag may individually be identified by the register contents that may be read or sent with
a doorbell.
