i.MX6 pad drive strength setting

[torus1000]

Hi,

Pad drive strength recommended 8mA on p2571 in i.MX6DQ RM rev2.0.

Which DSE setting is correct to drive 8mA @3.3V for SD4_CMD pad?

DSE=
001 150 Ohm @ 3.3V, 260 Ohm @ 1.8V
010 75 Ohm @ 3.3V, 130 Ohm @ 1.8V
011 50 Ohm @ 3.3V, 90 Ohm @ 1.8V
100 37 Ohm @ 3.3V, 60 Ohm @ 1.8V
101 30 Ohm @ 3.3V, 50 Ohm @ 1.8V
110 25 Ohm @ 3.3V, 40 Ohm @ 1.8V
111 20 Ohm @ 3.3V, 33 Ohm @ 1.8V

On th other hand, an IBIS model (gpiohv_ds001_sr000_mio:GPIO,3.3V,DSE=001)
shows Ioh@3.3=10.7mA.

Is it OK to set DSE=001 for 8mA current?

Thanks,

Hi torus1000

I think you are right,  DSE=001 for 8mA current

is proper selection.

Best regards
