Hi everyone,

I want to learn that how I can use InıSysPll() function. I saw function definiton in F2837xD_SysCtrl.c. But, I couldn't understand that how I can use it. What should be clock_source, imult , fmult and divsel values. How can I count them ? 

Thanks a lot ! 

Regards !

    hi Adem ,

    You can refer to the examples in the c2000ware .

    www.ti.com/.../C2000WARE

    eg. blinky example at  c2000ware\device_support\f2837xd\examples\cpu1\blinky\cpu01

    The InitSysCtrl(); calls the InıSysPll() function.

    eg. InitSysPll(XTAL_OSC, IMULT_20, FMULT_0, PLLCLK_BY_2);  These parameters can be modified as per the need.

    Details on what value to use can be seen in the TRM section 2.7.6 on Clock Source and PLL Setup

    Regards.
