Question
I have an application that requires very precise timing. Can I connect a
16.0000 MHz crystal to
the XTALO/XTALI pins and use this to clock the Cortex M3 core? If so, can you
recommend
values for the discrete components (R across crystal, C from each leg of
crystal to ground)
usually required by an internal oscillator?
Answer
If 1% over the temp-range is not accurate enough, than you can use an external
clock - not
crystal - on P1.0.
