请教关于F28M36的时钟配置问题!

Other Parts Discussed in Thread: F28M36P63C2, CONTROLSUITE

大家好!

 我现在正在使用Concerto系列的F28M36P63C2芯片,我看了conrolsuite中的例子,发现这个芯片的时钟配置都是设置在M3核运行在75MHz,C28核运行在150Mhz。我看手册上说这个芯片的M3核是可以运行到125MHz的,所以我想让芯片的M3核运行在125MHz同时C28核运行在150Mhz,该如何设置,外部晶振使用的是20MHz。

下面是controlsuite中的例子:

// Sets up PLL, M3 running at 75MHz and C28 running at 150MHz
SysCtlClockConfigSet(SYSCTL_USE_PLL | (SYSCTL_SPLLIMULT_M & 0xF) |
SYSCTL_SYSDIV_1 | SYSCTL_M3SSDIV_2 |
SYSCTL_XCLKDIV_4);
