pop the return address (where your program left to execute the interrupt) from the stack, and push a new return address on the stack and execute your RETI.

I did not really get it ? how would I know when and where external interrupt was executed, it could be anywhere in program as it can not be controlled.
Is it possible that you could write small routine here for me?

Many thanks
James
