Hi SIr,

Could you please help to clarify when DS125BR401A running at SATA3 6Gbps, what will we read MODE_DET Status?

I read the value as 00, is it correct?

Hi Anne,

These two bits detect incoming data rate. I am assuming MODE_B pin is floating? When this bit is floating then device determines PCIe gen data rate. So these bit indications may not be reliable for SATA3 applications.
