Can you please take a look and comment on this?
The accuracy of the RTC is stated as +/- 240 ppm, what should they do to change it to +/- 30 ppm? Also, if they want to compensate by temperature, what should they do?
Is there the ability to run the program while the Data Flash is being updated (erased + written)? (Can the program run with the update process deferred to the task?) Or will it be the time wait below during the update?
