I think this is not the case, particularly when using synch scsi.
In some circumstances (I forget what), the chip fails to flush
command bytes from the FIFO, but in others, it has incoming data
bytes in the FIFO. You must inspect the phase (and/or step?)
and decide whether the FIFO data is `good stuff' or `bad stuff'...
There is a reason I never got around to doing sync and disconnect, :-)
