Hi all,

I am currently fine-tuning my DDR performance, and i come across this MMDC_MDSCR (1Ch offset) register which is used to issue special commands manually towards the external DDR device.


However, the information in the reference manual is not much, and it certainly did not explains the types of special command, and how to use it.

May i know where can i find the information about this Core Special Command? Any explanation on how to set the register, what is the reason and effect on setting the register would be helpful.


Thank you.
