这是一个选择系统时钟的配置例子,这里其实就是给RUN0模式选择了FMPLL作为系统时钟。 FMPLL的工作需要有一个时钟源输入,而这个时钟源输入是不需要选择的,默认会是外部竞争。但是在前面的MExxMC寄存器配置的时候,应该把与外部晶振使能相关的寄存器设置为switch on。 这样,一个FMPLL的时钟配置就可以按照这个公式来做一...
混合型PLL—FM调制器 调制器混合型摘要:尾原昭博李群英旭光技术
This final Frequency could likely be lowered (say to 64MHz), if the FMPLL could be accelerated. With a lower initial Clock (say 40MHz, or even 32MHz). It would appear that the "FMPLL.ESYNCR1.B.EMFD" setting might affect how aggressively the FMPLL is able to lock, in...
