Page 35: Errata
This erratum is not applicable for AT91SAM9G20-EK Rev. C and later versions. Choice of an Oscillator Capacitance For many reasons at the manufacturing level, Atmel does not specify any crystal references at the board design stage. Because of that, the user can find an inconsistency in the value of the used capacitance of the 18.432 MHz crystal on each pin (C23, C24), and the nominal load capacitance of the crystal. - Page 36 Errata AT91SAM9G20-EK Evaluation Board User Guide 6413C–ATARM–18-Feb-09...
