Notes

80.Refer to the family-specific Architecture TRM for more information on crystal requirements (002-25800, TRAVEO™ T2G Automotive

Cluster 2d Family Architecture Technical Reference Manual (TRM)).

81.Oscillator startup time is a performance parameter and mainly depending on the chosen external crystal and load capacitance.
