Well, the question that sparked the conversation was Can F21 do POTS
mo-de-m with its 6 bits A/D and D/A converters @ 5 MHz sampling rate? 

The answer that I wanted to supports is Most probably yes, using
some analog circuitry, oversampling, and enough DSP power.

I.e., the 6-bit A/D D/A is most probably not an impediment (or _the-
impediment :-)
