AM62A7-Q1: How to RD (Read) DQ Calibration in DRAM?

Tool/software:

Hi,teams

Environment:

  SOC：AM62A7-Q1

  DRAM：Nanya NT6AN256T32AC-J1H

Question:

    For functional safety, we need to check the connection of DRAM pins (DQ). The following are the steps for DQ in Nanya datasheet:

  We did not find the relevant register in the AM62A7 TRM. How can we RD (Read) DQ calibration?
