K60 NFC command question

Hello Support Team,


I am using K60 with NFC interfacing to micron Nand Flash MT29F16G08ABABAWP-IT.  This NAND device has the features that user can select different timing mode.

I used the NFC_LDD and it gave me all the necessary hook to do page read, write, reset, read id, and block erase.

however, it does not give any other command for set/get features (see attachment for definition from Micron).  I can add these supports by myself, but i am a bit confused on how NXP NFC works.  I have a few questions:


1- What does NFC clock has to do with async NAND flash?  Is it being used for internal NFC operation only or it is actually used for NFC IO generation.  If it is, how should user configure it for proper NAND async operation?


2- NFC_CMD2[MODE] (see jpg) defines a sequence of NAND operation.  I can correlate that to the example (see jpg example) for page read, write, reset, block erase.
