MMCM2 using DRP : how configure params for SSC?

Hi,

 

I'd like to re-config. MMCM2 through Dynamic Reconfiguration Port & change Spread Spectrum parameter.

"Xilinx PG065 LogiCORE IP Clocking Wizard 4.2, Product Guide" shows how to configure SSC on Wizard, butdoesn'tdetailofDRP.

XAPP888 "MMCM and PLL Dynamic Reconfiguration" shows detail of DRP register of MMCM but not of MMCM2.

(MMCM not support SSC)

Does anyone know where I can get docs  of  MMCM2 DRP register details?

 

Thank you all.

Changing Spread Spectrum attributes via the DRP is not supported.

Hi, ralfk

 

Thank you for replying.

 

Anyway,

Are there any MMCM2 spec sheet about DRP?

Are they common with MMCM?
