Welcome in the forum!
I think that you need a quite reliable answer from Cypress directly.So I would suggest you to create a "MyCase". At top of this page -> Support & Community -> Technical Support -> Create a MyCase.
Two basic parts to FCC, conducted (battery operated usually not applicable) and
emissions. FCC will take under consideration prior approval reference
material, but still performs emissions unless its a module based approach
where module was certified for emissions. They are very cooperative, and
there are approved (if my memory serves me) external labs that can assist
customers w/o the expertise to meet standards. I would go to their web site
and look for 3'rd party support.
