SN75DP159: To swap P and N at input and output

Part Number: SN75DP159

Hi Sir,

May we swap P and N for input port and output port at the same time without any hardware or software efforts?

According to the below E2E DP149 thread, DP149 is okay for this requirement. 

https://e2e.ti.com/support/interface-group/interface/f/interface-forum/1202428/sn75dp149-swapping-p-and-n-on-input-and-output-to-facilitate-routing?tisearch=e2e-sitesearch&keymatch=DP159%252520P%252520N%252520swap#

Please help to confirm this requirement.

And the datasheet lane swap description is also talking about swap the polarity of P and N, but it looks the bit6 of register 0x9h should be set.

I think it is for lane swap, not for swapping P and N at the same time of input and output without lane swap.

Please help to clarify, thanks!

Thanks and Best regards,

Tiger
