I am confused. I can understand a holy way :
machine code .vs. assembly
but microdode is not really related to those, it relates to the internal
deisng of the processor control system. You cna of cours write microcode
in a form of assembly language, I've done so many times, and have written
several mcirocode assmeblers and diassemblers.
When does a 'state machine' become 'microcode' though? To a hardware
person they are very similar.

Microcode engines are a subset of state machines which read the state
transitions from an external memory instead of the transitions being
developed by random logic.
