Please tell me  about the question.


He recommended setting value is 1.
Why is this?

DRAM_Data is single-end signals.
So I think it is "CMOS input type" setting.




  bit17 DDR_INPUT
   DDR / CMOS Input Mode Field
   Select one out of next values for group: DDRMODE (Pads: DRAM_D[63:0]).
    0: CMOS input type
    1: Differential input mode (recommended)"
