Intel Atom DDR3 interface bit / Byte lane Swapping?

RSHAR3 — Fri, 03 May 2019 17:13:34 GMT

We are using Intel Atom E3826 in our design. To maintain DDR3 layout guidelines, we need to swap the data bits within the byte lane group. In the E3800 PCB layout guideline document, it is written that DDR3L bit / Byte lane swapping is supported.

Is there any restriction on the swapping of data pins (Ex; DQ0 - DQ7) within byte group?
