Welcome in the forum, Dante.
Because this is a developer forum it might take some time until a Cypress employee reads this. Better would be to create a support case:
At top of this page select "Design support -> Create a Support Case" and ask your question. You will be helped by a Cypress engineer.
The examples are directly part of PDL library (http://www.cypress.com/documentation/software-and-drivers/peripheral-driver-library-pdl?source=search&keywords=pdl)
Are you looking for any specific examples?
