3. The minimum and maximum tolerance values provided in the table are only for the frequency at which
the writer trims the HIRC oscillator. After trimming at this chosen specific frequency any change in
HIRC oscillator frequency using the oscillator register control bits by the application program will give a
frequency tolerance to within ±20%.
