AM6411: What's the right Spec. for SDIO?

Gibbs Shih
Expert 5245 points
Part Number: AM6411

Tool/software:

As title description, What is SDIO Spec? 

Does it support SDIO 3.0 or SDIO 4.0?

Because I saw something different.

In TRM, p23, it says support SDIO 3.0

But in TRM p8719, it says support SDIO 4.0

Which is correct one?

Thank You.

Gibbs

    Hello Gibbs,

    We verified the TRM content internally.

    The datasheet is correct and references to 4.x in the TRM will be updated.

    Regards,
