[time-nuts] Microchip PIC CTMU

It is always an extra challenge to get even datasheet performance out
of sampling converters which are integrated with a microcontroller and
of course Microchip says nothing about noise or complete AC
performance.

I suspect adding an external ADC to the Microchip CTMU while possible
would be a waste of effort.  If you are going to do that, then you
might as well design in a real time to voltage converter.
