I was assuming from original posts that this was a special case situation of _generating_ the data, not receiving it.

Perfectly legal. Also very common. Correct, but you cannot rely on this being the case when receiving. If you cannot do the necessary housekeeping in one stop bit time, expect trouble. You may be able to do some of the housekeeping during the next start bit with some clever programming, depending how much time is spent in the interrupt routine.
