Dear

I have a question about drive strength current for Ioh and Iol.

How to calculate drive strength current using DSE of I.MX6?

Or Can I get an information regarding drive strength current for I.MX?

Although I calculate using Iout=(VCC-VOH)/ZO, I didn't a credible result. I can't know whether the result is correct or not.

Thanks
