in the main loop for instruction decode there is a single instruction
dispatch function. Create a global counter (emulate_counter?) and
increment it once each time the dispatch function returns.
You can in the emulator redirect I/O port access to a function. Write the
code to handle read/write on those ports and use the emulate_counter to
drive the clock value.
