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.
