OK!
This is another example of the experience that in IT you cannot trust to what you learned some years ago. I always considered a machine instruction, i.e. an OP-Code to be executed completely, or not at all. Even if some micro software is involved. The possibility of interrupting within an instruction is new to me. However, I wonder what value is kept in the Program Counter for return from interrupt then.

I am sorry to have caused fuss. In the future, I will keep my two cents with me.
