Question about UART signals direction and route in i.MX6SoloX

Hi all

I have a question about UART module in i.MX6SoloX.
I'm confusing the direction and routing of the UART signals based on whether the UART is operating in DCE mode (UARTn_UFCR[DCEDTE]=0) or DTE mode (UARTn_UFCR[DCEDTE]=1).

So I want to clear it.

 

Here is a UART signals and direction table that is in general and refer from the Figure 65-2 of IMX6SXRM.

 

 

 

 

 

 

 

 

 

 

 

 

 

The part highlighted in yellow is different from general and refer from the Figure 65-2 of IMX6SXRM.

 

 

I think the Figure 65-2 of IMX6SXRM is wrong.

Am I wrong ?

 

 

Also I checked P5199 of IMX6DQRM, Table 90 of IMX6DQCEC and a following thread.

https://community.nxp.com/docs/DOC-97509

 

All of those UART signals direction and route are different.

Please tell me which direction and route are correct.
