Which AXi registers to write to configure DRP port of MMCM ?

Jump to solution

Hi Friends,

 

I used MMCM with dynamic reconfiguration enabled and AXI is the user interface.  This axi interface connected to Microblaze processor through AXI Interconnect. I got some address range like 0x44A0_0000(64K).

 

My doubt is which registers of AXI i have to modify in order to change the output frequency.

 

i have only one clock out(Default 100Mhz).

 

In XAP888 also not clear about AXI register set.

 

1) what are AXI (0X44A0_0000 is the base in my case)registers sholud i change to update DRP registers , so that i will get chnage in output(clock_out1) ?

2) I want to change output from 150MHz to 250MHz. Is it possible ?

 

Please help.

 

Any help or suggestions are highly appreciated.

 

Thank You

S Sampath
