TUSB322I: CC1/CC2 swapping

Part Number: TUSB322I
Other Parts Discussed in Thread: TUSB322

Hi

I read the datasheet (P.25) and the following post.

https://e2e.ti.com/support/interface/usb/f/1008/t/545905?tisearch=e2e-sitesearch&keymatch=TUSB322%20CC1

If the CC1 and CC2 is swapped, DIR pin is also connected as the following. (TUSB322 Fig 12)

On the other hand, if the CC1 and CC2 is not swapped, DIR logic should be inverted?

Or is there any other method?

Our customer would like to be connected CC1 and CC2 by straight(not swapped).  So that,we would like to find any way to be solved by hardware and software.

(TUSB322 P.25 )
