i.MX RT1050 GPIO output type?

Hello,

I have been looking at the MX RT1050 Datasheet, but I wasn't able to find a clear question to my question. 

Does MX RT1050 GPIO support both Push pull(CMOS) and open drain configuration?

On pg.32, there are electrical specs. for multiple pull up and pull down resistor values, but I couldn't find any explicit words that MX RT1050 supports both Push pull and open drain.

Could anyone help me out clarifying this? If both settings are configurable, where do I configure it?

 

Best Regards,

Hi,

Yes, i.MX RT1050 supports both CMOS and Open Drain configuration. You can enable Open Drain using ODE bit in IOMUXC_SW_PAD_CTL_PAD register. Please check the below snippet from the reference manual. For more information please check the GPIO chapter in RM.
