IMX8M Mini input transition time on GPIO

Sylvain_B — Mon, 23 Sep 2024 15:19:37 GMT

Hello,

I haven't found any specification for the transition time of GPIO inputs when CMOS input is selected with registers (Hysteresis Enable field bit disable).

Where can I find it?

Regards.

Hello @Sylvain_B

I hope you are doing well.

Unfortunately we have not documented your exact requirement but you can take a look to the AN5078 (Influence of Pin Setting on System Function and Performance).

Best regards,

Salas.

Hello,

Thanks your for your reply.

On the oscillograms, the horizontal scale ((??ns/div) is not visible. and this is not mentioned in the explanations. It's a pity, because if I'd been able to read it, I'd have been able to evaluate the input transition time.
