Hello,
As you might know, there are some of the documents and libraries which are under NDA (Non-Disclosure agreement) the information it's not public, the NXH2261 is one of this parts.
If you are already working with NFMI, I believe you should already have a contact that helped you getting the information, could you please contact that person for further support on this part ? If you do not have one that contact, could you please contact one of our distributors available in the Distributor Network|NXP to help you with your request
Regards
