i.MX 6 QP Select Input Register

Hi,

I design register settings for i.MX6QP.

Is it necessary to set Select Input Register only when one function is set to multiple Pads in Pad Mux Register?

Or is it always necessary to set Select Input Register even when one function is set to one Pad?

Hi Taiki

>is it always necessary to set Select Input Register even when one function is set to one Pad?

this depends on particular pad/function so necessary to check Chapter 36 IOMUX Controller (IOMUXC)

as in example below, ALT1 requires it, ALT0 - not :
