About setting pull up/down for GPIO output pin of i.MX6ULL

[hiectai]

Hello everybody.

I'm looking about setting up pull up/down for GPIO output pin for MX6ULL. I'm reading i.MX 6UltraLite Applications Processor Reference Manual. At Output Driver of chapter 26:
• Pull-up, pull-down, and pad keeper are disabled in output mode.
It means that the GPIO in output mode can not set pull-up / down?
Can I set up pull up / down with GPIO in output mode?

Thank you very much!

For MX6ULL, Reference Manual Chapter is 29.4.2.2

"Pull-up, pull-down, and pad keeper are disabled in output mode."

I suspect that this statement is FALSE, because in 29.4.2.2.4 "Open Drain", the usage of internal pull up is shown (see Figure 29-8).

So NXP has to clarify.

Hi!

It is possible.

And you set it in the 32-bit software pad control registers (IOMUXC_SW_PAD_CTL_PAD_<PAD_NAME>
