Hi Venkat Ratnam,
Hope you are doing great, as you may know the information about this is secured under NDA ( Non Disclosure Agreement) which means that all the documentation, tools and support should be done using secured communication channels and only to customers with active NDA. this can be downloaded from Docstore first you need to sign an NDA and request such documentation. to start such process please get in touch with an NXP sales team, you can contact your closest NXP office to get in touch and start this process.
