LAUNCHXL-F280049C: clock tree setting with SysConfig

Tool/software:

Hi all,

I'm using a LAUNCHXL-F280049C and need to configure an "odd" SYSCLK of 98.333 MHz. Clock source is 20 MHz XTAL.

Programming the system PLL with IMULT 14, FMULT 3 (resulting in 295 MHz VCO frequency), ODIV /3 and PLLSYSCLKDDIV /1 should work.

But SysConfig Clock Tree knows no ODIV and consequently complains about too high PLLRAWCLK of 295 MHz (max 200).


Here the Reference manual (SPRUI33H):

and here SysConfig clock tree, notice missing ODIV

I'm using CCS 12.8.1.00005, SysConfig 1.21.0.3721 and have imported empty_driverlib_project from C2000Ware_5_04_00_00\driverlib\f28004x\examples\empty_projects.

Is there any way to get the desired setting with SysConfig?

Regards,
Wolfgang
