"'Micro code' is not a program.......but the microcode is a table of steps the controller needs to take on the lowest hardware level "

That brings up an interesting question : So what is the real difference between a program and a table of steps ? Is not the latter more often referred to by the former nomenclature ?

Or is it that irrespective of the state of any I/O (!EA, ALE, PSEN etc ) all the steps of the so called table are executed ? Maynot be ..

Though this information is just academic to know, sounds quite exciting.
