AM335x Register for DDR slew rate configuration

Guru 15520 points

Hi,

I have a question about AM335x DDR register configuration.

In TRM(spruh73l) page.1460, there are ddr_cmd0_ioctrl register.

The question is about bit[9:8](io_config_sr_clk) of this register. It seems that this bit is Read-only.

How to configure Slew Rate? I guess it's typo and Read/Write is correct.

Is my guess right?

Because other ddr_cmdn_ioctrol bit[9:8] is R/W and it's description is written as follow:

///////////////////////////////////////////////////////////////

Only ddr_cmd0_ioctrl[9:8] are used to control io_config_sr_clk.

///////////////////////////////////////////////////////////////

best regards,

g.f.
