其实HCS12X的时钟很简单，比起ARM，甚至是HCS08的8位MCU，就是一个PLL和BUS COLOCK之间的换算。

很多不人愿意看DATASHEET，图太多了，寄存器也是样不多一个样子，所以往往导致程序出问题。

但是，时钟，CRG这块很重要，是一切模块的基础。

那么，如果你不愿意write code，那么就generate code吧。

-Fact, HCS12X clock is very simple compared to ARM, even HCS08 8-bit MCU is the between a PLL BUS COLOCK, the translation. So many people are willing to look DATASHEET Figure too much, the register is also kind of not much like, so often lead to procedural problems. However, the clock, CRG piece is very important, is the basis of all the modules. Well, if you do not want to write code, generate code.
