CC3100 32.768K晶振不起振

我起振电容尝试过10pf以及15pf，目前用示波器看都没有对应的波形 起振电容的电压 分别为0.6V 和0.8V

根据手册，The 32.768K XTAL should be placed closer to the QFN package. Ensure the load capacitance is tuned based on board parasitic so that the frequency tolerance is within ± 150 ppm.

另外，我们有40M晶振的频率调优文档可供参考： http://processors.wiki.ti.com/index.php/CC3100_%26_CC3200_Frequency_Tuning
