Other Parts Discussed in Thread: AM5718, AM5728

Hi,

There are following mentions in the technical reference manual of AM5718.
Table 26-9. SATA PHY Tuning Table
Table 26-17. USB3 PHY Tuning Table

It is Reserved when I refer to these Physical address in Table 2-3 L4_CFG Memory Map.

Is this an error in writing?

Physical address of TRM of AM5728 is like Reserved in the same.

Hi,

The registers located at these addresses are present/functional in the silicon but cannot be described in details in the public documentation. It is advised not to modify them.

If you wish to tune the SATA PHY or USB PHY you can write the values presented in Table 26-9 and Table 26-17 to the corresponding physical addresses.

Best Regards,
Yordan
