Depends what you mean by "real state". It doesn't necessarily correspond to a flipflop in the hardware implementation, but it's definitely state in our implementation. (Conversely, the hardware implementation has state which our s/w one does not, most notably we don't use the command and data state machine approach the hardware has.) > Can't it be recovered somehow from other state? No. -- PMM
