My guess, and I repeat 'my guess' is that the answer is 'yes'.

From the literature it seems that you can clock the SX-Ubicoms nearly down to zero and still have function as long as you provide adequate and stable power supply.  The software just runs at the rate the osillator is functioning at.

I suppose the only real question comes into play when the oscillator is not regular [if the rate is flucuating between fast and slow].  I suspect that even that might work it the duty cycle is roughly near 50/50.

I don't think stopping the oscillator is a good idea, but someone else would have to tell me why.  It is just a hunch.  If you could do it, you might be able to suspend the i/o ports in their various states indefinitely.

The real challange is to deterministically program the changes in the timing.  

Can you do that? Or do you even want to?

Sorry that I cannot offer more than mere speculation.  Maybe someone that has been there, done that will jump in.
