parallel port 1 on i.mx6 Dual-lite

Can the parallel port 1 be used on the iMX6 Dual-Lite (& solo)

 

Most of the documentation shows that the IPU can accept both Parallel Port #0 & Parallel Port #1
(e.g. IMX6SDLRM rev 2)

 

However, AN4397 (Common Hardware Design for i.MX 6Dual/6Quad and i.MX 6Solo/6DualLite) Rev 1, contains the rather worrying note:

"NOTE

Do not use Parallel 1 port as the video input when migrating an

i.MX 6Dual/6Quad hardware design to the i.MX 6Solo/6DualLite."

 

(In Chapter 8 Video input requirements for migration)

 

So, what is the reason for this?

 

If parallel port 1 cannot be used, then why is it mentioned in all the other documentation?

 

Thanks,

 

Phil
