Freescale recommends an evaluation of the application board and chosen
resonator or crystal by the resonator or crystal supplier.
The loop controlled circuit (XOSCLCP) is not suited for overtone
resonators and crystals.
Depending on the device package following device supply pins are maybe
combined into one pin: VDDR, VDDX and VDDA.
Depending on the device package following device supply pins are maybe
combined into one pin: VSS, VSSX and VSSA.
Please refer to the device Reference Manual for information if device supply
pins are combined into one supply pin for certain packages and which
supply pins are combined together.
An off-chip decoupling capacitor (100 nF...220 nF, X7R ceramic) between
the combined supply pin pair can improve the quality of this supply.
