Function imxrt_iomuxc::alternate
source · Expand description
Set an alternate value for the pad
Users who are using strongly-typed pads should not call alternate()
directly.
Instead, alternate()
will be used in a peripheral’s prepare()
function as needed,
so that you don’t have to call it.
However, you should use alternate()
if you’re using any type-erased pads, since those
pads cannot be used with a peripheral’s prepare()
function.
