Hi Sir/ Madam,


I am developing Pass-Through for NXP NTAG I2C 1K application (Datasheet NT3H1101_1201.pdf). 

I am struggling how to configure or write Pass-Through ( Bit #6 in NC_REG, inside session register).  I have try to write it, but it still remain as "0" when read back.  May I know what is the appropriate values of all the 7 register in session register, in order to be able to write a "1" into Bit #6 of NC_REG, of Session Register ? 

I do feel that there are certain bits and registers have to be configure first before this Bit #6 is able to be written.


For example, Bit #6 (I2C_LOCKED) of NS_REG, will be automatically set when Register WDT is written 0xFF. 

I have tried out many experiment to get this work, but still I am not able to get the result. 



Please help soon.



Thank you for your advice.
