My circuit works faithfully with its internal REFO of 32Khz, from wich i obtain a clock of 24.576Mhz.
I've seen that internal 32K reference has a precision of 1.5% and it is too much for a particular application.
Using a higher frequency crystal as external reference(for ex. 24.576MHz) is not advisable for its power consumption, so i'm planning
to use a 32KHz chrystal. I think that i need only to change the input to FLL:
UCSCTL3 = SELREF_2; to XT1CLK
set XCAP and leave all as it is.
Is that correct?
