About AM335x DDR register setting

Guru 15520 points

Hi,

I have a question about AM335x DDR_PHY_CTRL_1 Register.

It is about reg_phy_rd_local_odt.
There are "Full thevenin load" and "Half thevenin load".
What are the difference of these two thevenin load and
how to decide which to select.

best regards,
g.f.
