As you already have seen, the most general solution to your problem is to
check a 'not ready' bit that will be cleared in the interrupt-routine.
Another way could be, dependend on the Interrupt-source, to go into
'Sleep'-mode.  An interrupt will wake the system and you will continue
execution of your program.
