XE系列的datesheet里的CLKSEL_XCLKS位的说明为:
Oscillator Configuration Status Bit — This read-only bit shows the oscillator configuration status.
0 Loop controlled Pierce Oscillator is selected.
1 External clock / full swing Pierce Oscillator is selected.
寄存器CLKSEL的第五位,我都是按它的复位设置(0),没去管它,不知道不同的设置分别选中的是什么晶振,请弄过的指点下。 |
