A student remembers me going over the RTI instruction.  I don't remember
me going over the RTI instruction.  Just in case someone else does:

If I mentioned RTI at all, it was only in passing.  It is a very important
instruction (since I allocated one of my very precious 16 opcodes), but one
that is important in the context of dealing with interrupts, which we have
not studied yet.

So, please do not worry about RTI right now.  We will have plenty of time
to visit with RTI between the second midterm and the final exam.

Good luck on the midterm next Wedndesday.
