So if we’re using the internal oscillator, there is usually an associated calibration register.
If there is a reason for runnng “as fast as possible”, I might just pick the top value and throw it in there. I won’t know for fast it is till I measure it, but it should be the fastest I can get.
Likewise, if I want lower power, I might set the calibration to the lowest possible values...
Are ther non-obvious disadvantages to having the calibration register at “the extreme endpoints”?
Less stability perhaps?
