1. Other frequency limits may apply when external clock is being used as a reference for the FLL or PLL
2. Proper PC board layout procedures must be followed to achieve specifications.
3. Crystal startup time is defined as the time between the oscillator being enabled and the OSCINIT bit in the MCG_S register
being set.
