I do not really need to run at 7 MHz. I could run at 4M or slightly
slower, if needed.
Questions:
1) What are CPU frequency ranges available, if I use the 270K ROSC
(rather than the 100K) as you suggest below? Where is that table?
good question, i can't find it at the moment. i belive to remember that
it was in a datasheet where they listed the values of the internal RSEL
selections.
i do not remeber if the detailed temperature selections were documented
in a data sheet or if we made our own measurements.
2) do I need to re-run fll_adjust() from time-to-time as the device
changes temperature?
yes. it will be quicker that the first time on startup, but during FLL
adjusting you mighn not be able to receive on the serial port (especialy
when the RSEL range has to be changed)
