Freescale recommends an evaluation of the application board and chosen
resonator or crystal by the resonator or crystal supplier.
Loop controlled circuit is not suited for overtone resonators and crystals.
Full swing Pierce circuit is not suited for overtone resonators and crystals
without a careful component selection.
